vala: Disable unity builds
Our approach to unity builds with vala is broken, you cannot unify the
generated C files, as they contain duplicate symbols. We would need to
instead combine the files while they are still in their vala form, then
convert that to C and compile the unified C file.
This does not fix the linked issue, as this removed the ability to do
vala unity builds, but it does allow running vala with `--unity=on`.
