[PATCH 3/4] tests/cpu-policy: Rework Makefile

[Andrew Cooper <andrew.cooper3@xxxxxxxxxx>]

In particular, fill in the install/uninstall rules so this test can be
packaged to be automated sensibly.

Rework TARGET-y to be TARGETS, drop redundant -f's for $(RM), drop the
unconditional -O3 and use the default instead, and drop CFLAGS from the link
line but honour APPEND_LDFLAGS.

v2:
 * Drop -f's
 * Use %.o rather than *.o for Make level wildcards
