Fix tests when build fs does not support high-precision timestamps

* gnulib: Import nanosleep module.
* configure.ac: Remove STAT_HAS_NSEC substitution.
* src/tests/Makefile.am (TESTS_ENVIRONMENT): Stop exporting
STAT_HAS_NSEC.
(AM_CPPFLAGS, AM_CFLAGS, check_PROGRAMS, fspause_SOURCES,
fspause_LDADD): Add.
* src/tests/fspause.c: New file.
* src/tests/mandb-2, src/tests/mandb-3, src/tests/mandb-4,
src/tests/mandb-5: Call ./fspause rather than next_second.
* src/tests/testlib.sh (next_second): Remove.
* .gitignore: Add src/tests/.deps and src/tests/fspause.
* NEWS: Document this.
