Title: libvpx craft target in formula

Adjust the formula for libvpx to determine the correct target.
Add an option to build universal if the OS is Darwin 9.
Remove the option to --enable-postproc because it's always enabled
Set --disable-runtime-cpu-detect so it's detected during make.
Set --disable-examples as they are not installed by Homebrew.
Don't allow --gcov when compiling with Clang. Cleans up warnings.
Remove the O-level from cflags with Clang. Cleans up warnings.
This was tested on 32bit and 64bit Snow Leopard 10.6.8 using
all three compilers from XCode-4.0.2, and it was tested on Lion
using both compilers from XCode-4.2.1.
