Which issue(s) this PR fixes:
none

What this PR does / why we need it:
Fluent::WindowsFile passes win32 error codes to SystemCallError so that it doesn't show
correct message for them. For example when ERROR_SHARING_VIOLATION(32)
of win32 occurs, it shows Errno::EPIPE(32).

Docs Changes:
none

In fluent#3325 we added Win32Error to show Windows specific errors correctly,
but it's not enough for debugging because it doesn't show which file
causes the error.

### GitHub Vulnerability Alerts

####
[CVE-2021-41186](https://github.com/fluent/fluentd/security/advisories/GHSA-hwhf-64mh-r662)

### Impact
parser_apache2 plugin in Fluentd v0.14.14 to v1.14.1 suffers from a
regular expression denial of service (ReDoS) vulnerability. A broken
apache log with a certain pattern of string can spend too much time in a
regular expression, resulting in the potential for a DoS attack.

### Patches
v1.14.2

### Workarounds
Either of the following:

* Don't use parser_apache2 for parsing logs which cannot guarantee
generated by Apache.
* Put patched version of parser_apache2.rb into /etc/fluent/plugin
directory (or any other directories specified by the environment
variable `FLUENT_PLUGIN` or `--plugin` option of fluentd).

####
[CVE-2021-41186](https://github.com/fluent/fluentd/security/advisories/GHSA-hwhf-64mh-r662)

### Impact
parser_apache2 plugin in Fluentd v0.14.14 to v1.14.1 suffers from a
regular expression denial of service (ReDoS) vulnerability. A broken
apache log with a certain pattern of string can spend too much time in a
regular expression, resulting in the potential for a DoS attack.

### Patches
v1.14.2

### Workarounds
Either of the following:

* Don't use parser_apache2 for parsing logs which cannot guarantee
generated by Apache.
* Put patched version of parser_apache2.rb into /etc/fluent/plugin
directory (or any other directories specified by the environment
variable `FLUENT_PLUGIN` or `--plugin` option of fluentd).

### GitHub Vulnerability Alerts

####
[CVE-2021-41186](https://github.com/fluent/fluentd/security/advisories/GHSA-hwhf-64mh-r662)

### Impact
parser_apache2 plugin in Fluentd v0.14.14 to v1.14.1 suffers from a
regular expression denial of service (ReDoS) vulnerability. A broken
apache log with a certain pattern of string can spend too much time in a
regular expression, resulting in the potential for a DoS attack.

### Patches
v1.14.2

### Workarounds
Either of the following:

* Don't use parser_apache2 for parsing logs which cannot guarantee
generated by Apache.
* Put patched version of parser_apache2.rb into /etc/fluent/plugin
directory (or any other directories specified by the environment
variable `FLUENT_PLUGIN` or `--plugin` option of fluentd).
