These are valid expressions in the middle of a pattern in a .fc file, in
order to match an optional subdirectory level.
Some recent commits introduced "/([^/]+/)?" in the policy:
* commit b8f2c55109 ("cups: use ([^/]+/)? to match a subdirectory of
CUPS configuration")
* commit 4b02c2230d ("authlogin: label utempter correctly on Debian")

Writing .fc files without any mistake is quite hard. Sometimes a regular
expression pattern compiles fine but it does not match what is intended.
Add a script that detects some issues in .fc files. When this script is
used directly ("./testing/check_fc_files.py"), it checks the content of
policy/. The path to policy/ can also be provided by option -p.
