ZTS: Fix non-portable date format

The delegate tests use `date(1)` to generate snapshot names, using
the format '%F-%T-%N' to get nanosecond resolution (since multiple
snapshots may be taken in the same second).  '%N' is not portable, and
causes tests to fail on FreeBSD.

Since the only purpose these timestamps serve is to create a unique
name, simply use $RANDOM instead.
