Fix dumping role comments when using --no-role-passwords 

Commit 9a83d56b38 added support for allowing pg_dumpall to dump
roles without including passwords, which accidentally made dumps
omit COMMENTs on roles.  This fixes it by using pg_authid to get
the comment.

Backpatch to all supported versions. Patch simultaneously written
independently by Álvaro and myself.
