tests/plugins: replace rand_ish use with a counter

Browse source 
Rather than generating a random temporary file name for each plugin
generated by the test, just use a counter to ensure uniqueness.

This was the only remaining rand_ish user, so this change will allow the
removal of rand_ish.

BUG=None
TEST=cargo test --features=plugin
