[FaceRest] Remove needless brace
[FaceRest] Replace DataQueryOption with OperationPrivilege for DBClientUser::updateUser()

Since recent OperationPrivilege accepts userId for setting
privileges, we should use it directly.
Old OperationPrivilege didn't have userId.
[client][HatoholUserProfile] Add a missing argument for onLoadCb()
[HatoholUserProfile] Fix inappropriate reference of gloabl variable
[client] Don't show "ADD" and "DELETE" buttons on users & servers pages when the user doesn't have privilege.
[client] Fix wrong privilege check.

TODO: Add tests
[client] Don't show check boxes on servers & users pages when the user doesn't have privilege to delete records.
[client][users] Don't show "Privileges" column when the user doesn't have privilege to update users
[client][users] Add missing attributes to control show/hide privileges column
[client][users] Don't show edit links when the user doesn't have privilege to update users
[client][HatoholNavi] Show "Servers" page to all users.

Now edit buttons on the page are shown only for admin users.
