hghave: add "chg" flag to skip tests that can't be compatible with chg
Several tests fail with chg for several reasons such as loaded chgserver
extension, running uisetup() per server instead of per runcommand, etc.
Since these tests can't/shouldn't be changed to be chg friendly, we need
a flag to skip them.
This patch explicitly drops CHGHG environment if chg isn't involved. This
way, hghave can just check if CHGHG exists.
