fix: make udev_get_library_context available also for non-udev compilations

If compiling without udev_sync support, udev_get_library_context simply
returns NULL so we don't need to remember putting ifdef UDEV_SYNC_SUPPORT
in the code all the time we just need to check whether there's any udev
context initialized or not.
