Build package timeout increase to 2h
Build package timeout increase to 2h

Some package are reaching the timeout. For example, building
python-pandas (needed by Gnocchi) can take a little bit than 1h30.
It already built once, then the other times, it failed, as it took
a bit longer.

Increasing the timeout from 90 mins to 120 should make it possible
to build such backports.
