agent: New flag "qual" for the trustlist.txt.

* agent/trustlist.c (struct trustitem_s): Add flag "qual".
(read_one_trustfile): Rename arg "allow_include" to "systrust" and
change callers.  Parse new flag "qual".
(istrusted_internal): Print all flags.
* sm/call-agent.c (istrusted_status_cb): Detect the "qual" flag.
* sm/gpgsm.h (struct rootca_flags_s): Add flag "qualified".
* sm/certchain.c (do_validate_chain): Take care of the qualified flag.
