x264: add from meta-oe, update and tweak

This is required by the default configuration of libav being brought over
from meta-oe. Changes from the meta-oe recipe:

* Update to the latest revision from the stable branch (upstream does
  not seem to provide stable releases.)
* Add LICENSE_FLAGS = "commercial"
* Enable PIC to fix text relocation warnings and disable warning for
  i586 (since PIC can't be used there)
* Make SUMMARY value slightly shorter
* Indent SRC_URI consistently with other recipes in OE-Core

(From OE-Core rev: a3ca077285003fbc04d134e875a58a745271e47f)

+-march flag is not in CFLAGS so this will always default to -mcpu=cortex-a8
