Fixes
build and install core module with make

Build and install the kpatch core module with make and make install,
rather than building it every time with kpatch build.

The only downside to this approach is that the user has to make and make
install kpatch every time they get a new kernel.  But this is only
temporary, until the kpatch module is delivered in an RPM.
add usage command descriptions and help command
add install/uninstall commands
remove naming magic

Don't do any naming translation for now.

All commands will now take kpatch-foo.ko as an argument rather than foo.

remove quotes around for loop elements

Right now kpatch-build fails when more than one object
file has changed because the quotes around the for loop
arrays cause the for loop to execute only once for all
elements in a single string.

Remove the quotes around the for loop arrays so that the
for loop is execute for each element.
