autotools: fix AM_CONDITIONAL for HAVE_UDEV and HAVE_AUDIT

Ensure AM_CONDITIONAL is always defined when entering the
else-branch, even when the library is not found. Previously,
when with_udev=auto (default) and libudev was not available,
the conditional was never defined, causing a configure error.
