Subject: [PATCH] tests: convert epoll_create1.test from match_grep to
 match_diff

* tests/epoll_create1.c (main): Print expected output.
* tests/epoll_create1.test: Use match_diff instead of match_grep.
* tests/epoll_create1.expected: Remove.
* tests/Makefile.am (EXTRA_DIST): Remove epoll_create1.expected.
