[libstdc++] [testsuite] intro/names.cc: undef func on vxw7krn

The '#define func' added in 2021, to test that system headers don't
violate the user namespace, exposes such a bug in the vxworks sysLib.h
header, so add yet another such annotated workaround.

for  libstdc++-v3/ChangeLog

	* testsuite/17_intro/names.cc: Undef func on vxworks >= 7 in
	kernel mode.
