Added upstream patch to fix compile warning spam

Added FFmpeg-devel-avutil-mem-Fix-invalid-use-of-av_alloc_size.patch,
which gets rid of the compiler warning spam when building. Also updated
PKGBUILD and added a dep that namcap said was missing (libxv)

PKGREL bump should also fix incompatibility issues when installing x265
by forcing a rebuild against the new shared lib.
