Linux: rpm: Update openafs.spec.in to include changes to installed files

* Remove several files from the packaging manifest that are no longer
generated or included in the distribution, such as the DES header
files.
* Exclude the aklog_dynamic_auth man page, since it is AIX-only
* Add new files that have appeared in the distribution, such as the
'afsio' binary.
* Add librokenafs.so.1 and libafshcrypto.so.1 to the base package,
because many of the binaries in the base package are linked against
librokenafs and the 'butc' binary is linked against libafshcrypto.
* Move the librokenafs.{so,a} and libafshcrypto.{so,a} to the -devel
package instead of the authlibs-devel package, now that the .so.1
library is part of the base package.
* Set the executable bits on the libraries installed in libdir.  This
change is important because it causes 'rpmbuild' to generate Provide
tag metadata for the libraries in the package, which is necessary now
that some binaries in other packages have generated Requires tags for
libraries packaged in the base package.  'rpmbuild' will not generate
the Provides tag if the libraries lack executable permission.
