The "runpath" check of rpminspect raises an error related
to DT_RPATH using /usr/lib64/samba for /usr/lib64/samba/pdb/ipasam.so.
This can be waived as ipasam.so is a plugin for smdb and
requires to have DT_RPATH set.
Add the path /usr/lib64/samba to the list of allowed DT_RPATH
to ignore the issue.
