Many architectures has a similar install.sh script.

The first half is really generic; verifies that the kernel image and
System.map exist, then executes ~/bin/${INSTALLKERNEL} or
/sbin/${INSTALLKERNEL} if available.

The second half is kind of arch-specific. It just copies the kernel image
and System.map to the destination, but the code is slightly different.

This patch factors out the generic part into scripts/install.sh.
