tests: stop tracking tests/gpg/random_seed

test-gpg.t left the random_seed file as modified. That was slightly confusing
... and it was accidentally changed in ea4996754d91.

The seed is created on demand and there is no reason to track it. There is also
no reason to leak state between test runs so we let the test clean up after
running.
