tests: make test suite more immune to environment variables

Plenty of tests break when "make tests" is run while environment
variables "HGPLAIN" or "HGPLAINEXCEPT" are set (test "test-obsolete-
checkheads.t" is just a single example).

This patch causes script "run-tests.py" to also remove these two
variables from the environment the tests are executed in.
