systemd needs this so special characters (like the ones in wireguard units that appear because they are part of base64) can be escaped using the \x syntax. Root of the issue is that `glob()` handles the backslash internally which is obviously not what we want here. Also add a test case and fix some perlcritic issues in the subroutine.
