Subject: [PATCH] kbuild/mkspec: support 'update-bootloader'-based systems

From: Jiri Kosina <jkosina@...e.cz>

When uninstalling kernel RPM, we're unconditionally calling 
"new-kernel-pkg --remove". This is useless on systems which are based on 
'update-bootloader' script instead.

Support update-bootloader removal method as well in case the script is 
present; contrary to new-kernel-pkg, this needs to be done in %postun, 
otherwise update-bootloader will refuse to remove entry for kernel for 
which the binary still exists.
