linux_client_unittest_shlib: fix cleaning

The EXTRA_PROGRAMS knob does not automatically trigger clean up of
targets listed in it.  Use CLEANFILES so we make sure `make clean`
will delete the linux_client_unittest_shlib lib.

Do you need to do anything do deal with .dwo files if the user asked for
-gsplit-dwarf?

If “make clean” doesn’t handle this for non-“extra” programs either, then it’s
fine to not handle it for this.

`make clean` does not delete any .dwo files currently.  i can post a new CL to
fix that for all targets.

LGTM

If it’s not standard for autotools “make clean” to deal with that, I don’t think
we need to be concerned either.
