Convert symlinks to straight files for 2 conffiles

Convert the survey_info.conf and dpdf_params.conf configuration files from
symlinks to straight files for the release.  In particular, turn the
survey_info.conf file into the blank version.  The BGPS_V2 file is still extant
in the repository for reference.
