rpminspect: add automatic waiver for runpath check

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.
