kpatch: do not rm selinux rpm owned directory

As part of the kpatch rpm package installation, the /var/lib/kpatch directory

gets created and is set to be selinux owned by the kpatch rpm package.

There is a problem where uninstalling the last kpatch-patch will also remove

this directory. When another kpatch-patch installation occurs, the

/var/lib/kpatch get recreated but withtout the selinux context which triggers a

policy error.

Since /var/lib/kpatch is now created by the rpm spec file, do not remove it

from the uinstall target of the kpatch script. This insures selinux context

consistency.

RHEL-only.
