Libyuv (#4948)

* add libyuv

* * add checksum for patch
* remove unused build arguments
* generate a pkgconfig file

* oops: fix missing prefix for pkgconfig file

* make this package git sourced

* move pkgconfig file to a source file
* update patches for latest git version
* switch to a github mirror as googlesource.com times out
