Auto merge of #2639 - sunfishcode:sunfishcode/linux-super-magic, r=Amanieu

Consolodate the Linux `*_SUPER_MAGIC` constants.

Move the Linux `*_SUPER_MAGIC` constants out of
android/uclibc/gnu-specific directories and into the common `linux_like` directory
so that they're available on all Linux-family platforms, and so that that all
Linux-family platforms have all the constants.
