[pve-devel] [PATCH access-control 2/3] permissions: fix token/user priv intersection

["Fabian Grünbichler" <f.gruenbichler@proxmox.com>]

the token/user priv intersection could only honored user privs that had
the propagation flag set, reducing the scope of the token more than
intended.

the pre-existing test case actually triggered the broken behaviour, but
the expected value matched it so it was not noticed.

Fixes: e8a0cee47bb477162f291e67144ea0c0df47f2ee "rpcenv: improve user/token intersection"
