Do not pass -dead_strip to ld for the Mac helper and main apps.

On certain SDK versions and OSes with the 10.6 deployment target, the linker, if
invoked with -dead_strip, incorrectly removes _NXArgc and _NXArgv. Since the
apps are just shims into the Framework, there's little to strip anyways.

BUG=139902
TEST=Build on 10.7+ with GYP variable mac_strip_release=1.
