(PUP-12047) Add logic to skip MD5 checksum method on a FIPS system

[AriaXLi]

This commit adds logic in http_metadata.rb to skip MD5 related checksums when FIPS is enabled since MD5 is not supported on FIPS enabled systems. This PR addresses #9375.

I was able to successfully re-produce the error on a RHEL 7 FIPS machine:

[root@slower-bedstraw ~] cat another_test.pp
file { '/tmp/test':
        ensure => file,
        source => "https://github.com/voxpupuli/webhook-go/releases/download/v2.6.1/webhook-go_2.6.1_linux_amd64.deb",
      }
     
[root@slower-bedstraw ~]# puppet apply another_test.pp
Notice: Compiled catalog for slower-bedstraw.delivery.puppetlabs.net in environment production in 0.01 seconds
Error: /Stage[main]/Main/File[/tmp/test]: Could not evaluate: Parameter checksum failed on File[/tmp/test]: MD5 is not supported in FIPS mode (file: /root/another_test.pp, line: 1)
Notice: Applied catalog in 0.55 seconds

With my changes the error goes away:

[root@slower-bedstraw ~]# puppet apply another_test.pp
Notice: Compiled catalog for slower-bedstraw.delivery.puppetlabs.net in environment production in 0.01 seconds
Notice: Applied catalog in 0.67 seconds

@AriaXLi it looks like the backport failed, were you or @cthorn42 going to manually backport?
