posixtm-tests: revamp
Record only the expected time_t value, not the ctime string.
Skip any test that would require a time_t value larger than
currently representable (e.g., if run with 32-bit time_t,
this skips any test that expects an out-of-range value).
* tests/test-posixtm.c (struct posixtm_test) [valid, t_expected]:
New members.
[expected]: Remove member.
(T): Include new column: valid. Move date strings into comments.
(main): Adapt.
Print a diagnostic for each skipped test.
Don't skip the entire test (exit 77) if time_t is unsigned.
Instead, skip only the individual tests with a negative result.
