meson: detect opengl api from -base .pc files correctly

There was a mismatch between the .pc files generated by
autotools and by meson that would lead to meson not detecting
that opengl api is available even though it is. This could
lead to build failures when building -bad with meson against
a -base that was built with autotools. The mismatch has now
been rectified but we will still check the old one for backwards
compatibility.
