From bug 1246633 and https://www.reddit.com/r/firefox/comments/45yhbm/4402_graphics_glitches_and_hanging_after_half_an - it looks like accelerated skia canvas on 10.7 is still bad. Disable it on anything less than 10.8

Revert to pre-44 behavior for older versions of OS X. 
Sounds better for users than the reported flickering problems.

Lame cc from bug 1249312

I am very unhappy to see this kind of uplift request that late in the cycle.
Next time, please be on top of your features, Bug 1244569 has been reported a month ago :/
Taking it for the only reason that 45 is an ESR.
