igt/gem_userptr: Check read-only mappings
Setup a userptr object that only has a read-only mapping back to a file
store (memfd). Then attempt to write into that mapping using the GPU and
assert that those writes do not land (while also writing via a writable
userptr mapping into the same memfd to verify that the GPU is working!)
v2: Pull the random batch construction into a routine to avoid
duplication.
