Updated RedHat RPM spec file to include unreferenced files

Updated RedHat RPM spec file to include unreferenced files

Added the libkopenafs libraries and headers to the authlib package.

Added the afs_compile_et binary to the devel package

Removed the reference to .../man5/afszcm.cat.* because it is already
caught by the earlier reference to .../man5/afs* glob.  This caused a
warning during the package build process.
