tests: avoid test failures due to new EGREP_TRADITIONAL

Some tests require that filtered pre- and post-test
environments be identical. The filtering removes assignments
to known (set-by-test) envvar names, like GREP, SED, YACC.
* tests/local.at (_AT_CHECK_ENV): Also filter out assignments to
EGREP_TRADITIONAL, added in v2.72a-35-g0c762675.
