GetUserId() changes to has_privs_of_role()

The pg_stat and pg_signal-related functions have been using GetUserId()
instead of has_privs_of_role() for checking if the current user should
be able to see details in pg_stat_activity or signal other processes,
requiring a user to do 'SET ROLE' for inheirited roles for a permissions
check, unlike other permissions checks.

This patch changes that behavior to, instead, act like most other
permission checks and use has_privs_of_role(), removing the 'SET ROLE'
need.  Documentation and error messages updated accordingly.

Per discussion with Alvaro, Peter, Adam (though not using Adam's patch),
and Robert.
