Subject: [PATCH] tests: zgrep-context assumes grep knows context

* tests/Makefile.am (TESTS_ENVIRONMENT): Pass GREP too.
* tests/zgrep-context: Check that the underlying grep supports
context options.  Problem reported by Steven M. Schweda in
<http://lists.gnu.org/archive/html/bug-gzip/2013-06/msg00010.html>.
