tests: workaround old gawk versions that do not provide @include support

Some of our tests use GNU awk @include extension, but not all currently
used versions of GNU awk support it.  Skip these tests if gawk does not
provide @include support.

* tests/init.sh (check_gawk): New function.
(match_awk): Use it.
