dirmngr: Use "pgpkey-hkps" and "pgpkey-hkp" for SRV record lookups.
* dirmngr/ks-engine-hkp.c (map_host): Chnage arg NO_SRV to SRVTAG. (make_host_part): Rewrite.
This fixes a regression from 2.0 and 1.4 where these tags have been in
used since 2009. For whatever reason this was not ported to 2.1 and
"hkp" was always used.
