ITS#8928 Reproducibility: Remove user, hostname, pwd from version string

When attempting a reproducible build, replace the WHOWHERE value with something
fixed, "openldap". If you're not trying to do a reproducible build,
SOURCE_DATE_EPOCH won't be set, so the existing WHOWHERE string will apply.
See https://reproducible-builds.org/specs/source-date-epoch/
