[issue5588] Add --randseed to regrtest

[Collin Winter]

New submission from Collin Winter <collinw at gmail.com>:

Add the ability to control the random seed used by regrtest.py -r. This
patch adds a --randseed option, and makes regrtest.py -r indicate what
random seed it's using so that that value can later be fed back to
--randseed. This option is useful for tracking down test order-related
issues found by make buildbottest, for example.
