Subject: [PATCH] scripts/rebuild-rhel-kernel-rpm: Remove this script

Since rebuilding the RHEL kernel is no longer recommended, remove the script
that rebuilds the RHEL kernel RPM.

-# The recommended way to use this script is as follows:
-# - Create an additional user, e.g. builder
-# - Add a line to the sudoers file that allows that user to invoke yum and
-#   yum-builddep. One way to do that is by invoking the following shell
-#   commands as root:
-#     useradd builder
-#     echo 'builder ALL=(ALL) NOPASSWD: /usr/bin/yum, /usr/bin/yum-builddep' >>/etc/sudoers
-#     visudo -sc
