xf86-video-ati: Update 19.1.0 -> 19.1.0+7a6a34af

The ATI/AMD Radeon video driver for the Xorg X server

- Switch to git in SRC_URI
This video driver hasn't released any package in the last 2+ years.
Switch recipe to use git instead of release tarball to get the latest
version of it.

- Drop patches already upstreamed.

- Add PACKAGECONFIG support: udev and glamor.

- Add mesa driver runtime dependencies and libegl as glamor runtime dependency.

- Add ${PN}-config package.

- Fix mesa RDEPENDS. The radeonsi, r600, r300 and swrast are part of
the mesa-megadriver package.
