pipe-loader: Build kmsro loader for with all kmsro targets

Build failure reported by i965 CI, triggered by building dynamic
pipeloaders with kmsro drivers (besides 'frost). At this point, there's
no reason to actually do that -- mesa CI didn't mind -- but let's not
break the build.

v2: Simplify script. Add extra dependencies for v3d.

Fixes: afb0d08cb0 ("pipe-loader: Default to kmsro if probe fails")
