Fix goma regex detection and add optional nice launching

Here we add slightly improved detection for the goma flag.
The detection of goma in autoninja does not work for the use_goma flag
when it does not simply appear at the beginning of the line.

Below are examples of multi-arg lines we now support:
is_debug=false use_goma=true is_official_build=false
use_goma=false# use_goma=true This comment is ignored


Also adding linux nice process launch feature to improve the user
experience when running a large build. This feature is disabled by
default like other autoninja features.
