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.
version: enable pager if --verbose is specified
`hg version` output is very short without --verbose, but with
--verbose it tends to scroll off the user's screen.
