kbuild: refactor scripts/Makefile.modinst
scripts/Makefile.modinst is ugly and weird in multiple ways; it specifies real files $(modules) as phony, makes directory manipulation needlessly too complicated. Clean up the Makefile code, and show the full path of installed modules in the log. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
