semanage: Fix parsing of ignoredirs

From /etc/selinux/semanage.conf from a RHEL 9.1 system, this line
caused problems:

  ignoredirs=/root;/bin;/boot;/dev;/etc [...]

Parse this as a list of Rx.fspath.

Also this adds the RHEL 9 file as another test case and adjusts the
output of the existing test case.

+# The four options are:
+#
+#  "source"     - libsemanage manipulates a source SELinux policy
+#  "direct"     - libsemanage will write directly to a module store.
+#  /foo/bar     - Write by way of a policy management server, whose
+#                 named socket is at /foo/bar.  The path must begin
+#                 with a '/'.
+#  foo.com:4242 - Establish a TCP connection to a remote policy
+#                 management server at foo.com.  If there is a colon
+#                 then the remainder is interpreted as a port number;
+#                 otherwise default to port 4242.

+# When generating the final linked and expanded policy, by default

+# If you want to use a different home directory, you will need to use semanage fcontext command.
