tools: Move a function from gpg-wks-server to wks-util.c.

* tools/gpg-wks-server.c (list_key_status_cb): Remove.
(list_key): Move to ...
* tools/wks-util.c (wks_list_key): here and rename.  Add new args
R_FPR and R_MBOXES and remove the CTX.
(list_key_status_cb): New.
* tools/wks-util.c: Include ccparray.h, exectool.h, and mbox-util.h.
* tools/gpg-wks-server.c (process_new_key): Replace list_key by
wks_list_key.
(check_and_publish): Ditto.
