Hello everyone!

In picom upstream, they have accepted certain PRs that I made in order
to compile picom v11 on OpenBSD. All of this is being carried out in
the next and libepoxy branches.

This update has a small backport of the patches (maintaining
consistency with upstream code) and applies them to compile picom-v11.1.
Tested on my machine without problems (amdgpu, RX580, OpenGL backend).

Feedback is welcome.
