temp/mesa-*: remove suffix in pkgconfig version (!744)

Fix build with current abuild version by removing the "-devel" suffix
in /usr/lib/pkgconfig/*.pc. Set "pcprefix" instead, so abuild doesn't
confuse these packages with the regular mesa.

[ci:skip-build]: already built successfully in CI
Fixes: #386
