run-tests: allow whitelisting tests that should always run

It's desirable to run some tests all the time, for example
test-check-pyflakes.t and test-check-code-hg.py. This allows passing
--whitelist as a path to a file (flag can be specified more than once)
which contains a list of files to whitelist. Whitelisted tests are run
even if they're blacklisted or wouldn't match a --keyword test
run. For example, to do a quick test of usehttp2, one can now do

  $ cat > test-whitelist <<EOF
  > test-check-pyflakes.t
  > test-check-code-hg.py
  > EOF
  $ (cd tests && ./run-tests.py --extra-config-opt 'ui.usehttp2=true'
  >                             -k http -j 8  --whitelist test-whitelist)

and have all http-specific tests run as well as the two code linters.

  $ hg init
  $ touch a

  $ unset HGUSER
  $ echo "[ui]" >> .hg/hgrc
  $ echo "username= foo" >> .hg/hgrc
  $ echo "          bar1" >> .hg/hgrc

  $ hg ci -Am m

  abort: username 'foo\nbar1' contains a newline

  $ rm .hg/hgrc

  $ HGUSER=`(echo foo; echo bar2)` hg ci -Am m
  abort: username 'foo\nbar2' contains a newline
  
  [255]
  $ hg ci -Am m -u "`(echo foo; echo bar3)`"
  transaction abort!
  rollback completed
  abort: username 'foo\nbar3' contains a newline!
