Add DNSRPS builds to pairwise testing

The --enable-dnsrps-dl switch for ./configure enables preparing a
DNSRPS-enabled build of BIND 9 that is not directly linked against a
DNSRPS provider library (dlopen() at runtime is used instead).  Employ
this switch to test DNSRPS-enabled builds in the pairwise testing job in
GitLab CI.
