This will avoid undesirable interactions with the python sitedir,
as reported in bug 574002. Since the temporary HOME is not guaranteed
to exist for some phases, use PORTAGE_PYM_PATH as a fallback. Also,
use PORTAGE_PYM_PATH inside __dyn_clean, since HOME is removed there.

No real opinion -- not familiar enough with this to suggest alternative
solutions. Patch itself looks OK.
