tests: replace non-portable "date +%s" with ruby equivalent

"date +%s" is not in POSIX (it is in GNU, and at least FreeBSD
9.0, possibly earlier).  The Ruby equivalent should be
sufficiently portable between different Ruby versions.

This change was automated via:
	perl -i -p -e 's/date \+%s/unix_time/' t/*.sh
