run-tests.py: inherit --pure option from outer run-tests.py execution
Before this patch, "test-run-tests.t" doesn't test "run-tests.py" with
"--pure", even if outer "run-tests.py" is executed with it.
This patch uses not "HG_RUN_TESTS_PURE" but "HGTEST_RUN_TESTS_PURE",
because "HG_" prefixed environments are forcibly dropped in "_getenv()".
This is also useful to run "run-tests.py" successfully by
"run-tests.py --pure" on Windows without any compilation tools (like
VisualStudio).
