>Description:
Fix the following issues in tests/lib/libc/regex/:

t_exhaust.c: make the test case more robust.

- Limit memory to 64MB.
- Require 64MB on the test host.
- Sort headers.

t_regex_att.c: use ATF_CHECK_STREQ_MSG instead of ATF_REQUIRE_STREQ_MSG, so all errors with t_regex_att could be captured by the tester.
