Bug 1207752 - Increase how long we let incremental GC run before forcing it to finish. r=smaug

Browse Source 
Some users with many tabs have reported extremely long GC pauses
triggered by the CC forcing the GC to finish. Increasing the limit may
cause memory to be somewhat higher for these users, but that is better
than 30 second pauses.
