makepkg: implement support for stripping kernel modules

I noticed when I built a kernel package with options 'strip' and 'debug' that
the debug package was missing the debug information for the kernel modules.
This patch adds kernel modules to the targets for 'strip' and is compatible
with the split-out debug information packages.

v2: Correct logic error -- did a 'continue' after the 2nd-level case statement
    instead of in the default case.
v3: Oops, forgot to terminate outer case. Ran this version through the test
    suite and all tests passed.
