Subject: [PATCH] tests: save/restore Autotest special files when checking XML
 support.

Currently the test 248, "parse-gram.y: LALR = IELR", fails
BISON_TEST_XML is set.

* tests/local.at (AT_BISON_CHECK_XML): Belt: Save/restore files.
* tests/regression.at (parse-gram.y: LALR = IELR): Suspenders: Don't
rely on expout.
Each one of these changes suffices.
