doc: Clarify requirements for SET ROLE.

Since commit 3d14e171e9, SET ROLE has required the current session
user to have membership with the SET option in the target role, but
the SET ROLE documentation only mentions the membership
requirement.  This commit adds this important detail to the SET
ROLE page.
