build: silence recent syntax check violations

An upstream gnulib bug[1] meant that some of our syntax checks
weren't being run.  Fix up our offenders before we upgrade to
a newer gnulib.

* src/util/virnetdevtap.c (virNetDevTapCreate): Use flags.
* tests/lxcxml2xmltest.c (mymain): Strip useless ().
