BUG/MINOR: resolvers: do not reject host names of length 255 in SRV records

An off-by-one issue in buffer size calculation used to limit the output
of resolv_dn_label_to_str() to 254 instead of 255.

This must be backported to 2.0.

(cherry picked from commit 85c15e6bff92c2dae609d76f72c1d231d048dd74)
