Fixed bug 3503 - osx builds don't run on 10.6 as of rev. 10651

Ozkan Sezer

With rev. 10651, i.e. http://hg.libsdl.org/SDL/rev/747a6a795b21 ,
SDL2 - OS X builds fail to run on 10.6 (my setup: i686 / 10.6.8)
because the symbol _IOPMAssertionCreateWithDescription is missing.
The SDK listing it for 10.7+ does seem correct.  Reverting r10651
and rebuilding makes it to function again.
