The 'httpd' package actually contains the mod_proxy.so as
/usr/lib64/httpd/modules/mod_proxy.so.  Running
'repoquery -f /usr/lib64/httpd/modules/mod_proxy.so' will generate the
correct response.

RPM, on the other hand, has the benefit of having a local filesystem
with the actual files installed.

One of the first things that the 'rpm' command does is stat() the path 
/etc/httpd/modules, discover it's a symlink, and then run the actual
path /usr/lib64/httpd/modules/mod_proxy.so through the RPM database.
The command is going to pass the 'real' location (as best it can find)
for any query with file paths.  'repoquery' doesn't have the benefit
of having the package installed, so it can't perform this local
lookup.  It has to rely only on what the package manifest lists.
