Makefile: Allow "make modules_install" to work from top-level directory.

INSTALL recommends running "make modules_install" but it didn't mention
that this has to be done from datapath/linux.  This commit makes this work
from the top-level build directory.

(Another solution would be to update INSTALL, but this approach seems a
little easier for the user.)
