Subject: [PATCH] Make python changes more reliable
We oneshot emerge without calculating dependencies a few things to solve
for possible dependency loops.
Python 3.5 also became stable, so don't need to do special things for
it.
Matched the uninstall with the install lines (no need for a full if
statement).
