Fix cmds Makefile to install all entries in SCRIPT_TARGETS

Prior to this CL the Makefile only installed entries that have a platform
specific suffix. It is far more scalable to choose targets based on
capabilities, which the Makefile now does and populates SCRIPT_TARGETS from
that (e.g. castcheck). Therefore, there is no point in ignoring non-suffixed
targets.
