[PATCH] scripts/prune-kernel: Use kernel-install if available

[Reza Arbab <arbab@linux.ibm.com>]

If the new-kernel-pkg utility isn't present, try using kernel-install.
This is what the %preun scriptlet in scripts/package/mkspec does too.

Hope I've sent this to the right people. get_maintainer.pl came up
blank, but kbuild seems like the nearest match in MAINTAINERS.
