Distribute egg-info files with rpms and debs

This merge modifies the glue.spec and debian/ files such that the lscsoft_glue-*.egg-info directory is included in the packages distributed by .rpm and .deb.

This change will mean that pip can see that these packages are installed, so that downstream python packages that declare a depenendency on lscsoft_glue don't end up installing it again (or having their installation fail).
