Add ATF_REQUIRE_FEATURE and PLAIN_REQUIRE_FEATURE macros for
testing for kernel features via the feature_present(3) libcall

The semantics are similar to the other macros in the header (skip
testcase with ATF macro; exit with appropriate exit code with the
PLAIN macro)

Fix typo. It should have been atf_tc_skip, not atf_skip

Reported by: many, Jenkins

MFC after: 4 days

ATF_REQUIRE_KERNEL_MODULE: use atf_skip, not ATF_REQUIRE_MSG so the testcase
no longer bombs out
PLAIN_REQUIRE_KERNEL_MODULE: use printf + _exit, no err so the testcase no
longer bombs out if it prints to stderr

MFC after: 5 days

Add initial (unpolished) macros for interfacing with the FreeBSD test suite

This is very rough, but will be replaced/redesigned some time soon after I fix
the Jenkins breakage I introduced
