Unnecessary Obsoletes: in rpm spec files

Some of the ldas-tools packages obsolete the older versions of itself:

Obsoletes: %{name} < %{version}

This is not necessary. A package will naturally obsolete the older version of itself when upgrading. The Obsoletes tag is usually reserved for when one package completely replaces the functionality of another with a different name. The packages that I noticed with this issue include:

• ldas-tools-diskcacheAPI-swig
• ldas-tools-framecpp-swig
• ldas-tools-ldasgen-swig
• ldas-tools-frameAPI-swig
