cairo, pixman: upgraded packages to upstream

Upgraded x11-libs/cairo to version 1.12.12 on amd64, arm, x86
Upgraded x11-libs/pixman to version 0.28.2 on amd64, arm, x86

These had to be done together due to version interdependencies.

In both cases, the respective ebuild files differ from their
upstream versions only as follows:

  () Edited EAPI 5 down to EAPI 4
  () Edited KEYWORDS to mark amd64, arm, x86 as stable

TEST=Build chroot with clean repo and run available media test
