kbuild: unify modules(_install) for in-tree and external modules
[ Upstream commit 3e3005df73b535cb849cf4ec8075d6aa3c460f68 ]
If you attempt to build or install modules ('make modules(_install)'
with CONFIG_MODULES disabled, you will get a clear error message, but
nothing for external module builds.
Factor out the modules and modules_install rules into the common part,
so you will get the same error message when you try to build external
modules with CONFIG_MODULES=n.
