Don't create compatibility suite copy rules for installed path

Don't create compatibility suite copy rules for $(LOCAL_BUILT_MODULE)
to $(LOCAL_INSTALLED_MODULE), as that could conflict with a Soong
install rule.  Instead, always create the install rule the normal way,
and replace the compatibility suite copy rule with a noop if it is the
same as the normal rule.
