selftests: kallsyms: fix double build stupidity
The current arrangement will have the test modules rebuilt on
any make without having the script or code actually change.
Take Masahiro Yamada's suggested fix and cleanups on the Makefile
to fix this.
Suggested-by: Masahiro Yamada <masahiroy@kernel.org>
Reported-by: Linus Torvalds <torvalds@linux-foundation.org>
Fixes: 84b4a51fce4ccc66 ("selftests: add new kallsyms selftests")
Closes: https://lore.kernel.org/all/CAK7LNATRDODmfz1tE=inV-DQqPA4G9vKH+38zMbaGdpTuFWZFw@mail.gmail.com/T/#me6c8f98e82acbee6e75a31b34bbb543eb4940b15
