udev: make use of udev_enumerate_add_match_tag() only when it is available

Browse Source 
udev_enumerate_add_match_tag() and udev_monitor_filter_add_match_tag()
are mostly optimizations, hence simply skip these calls if they are not
available in the installed version of libudev.

This should fix the build on older versions of udev.
