Fix spurious destroy during RPC to self with rendez-vous
In that case we have two receive right references, which we should consume
one per one, instead of destroying them all at once (and thus fail on second
destroy)
http://lists.gnu.org/archive/html/bug-hurd/2011-03/msg00045.html
* libfshelp/fetch-root.c (fshelp_fetch_root): Unreference rendez-vous port
receive right instead of destroying the port.
* libshouldbeinlibc/exec-reauth.c (exec_reauth): Likewise.
