[Peter Bloomfield <peterb src gnome org>]

commit cc36b2348960d0b40e28155038ddcd7cb11d9e13
Author: Peter Bloomfield <PeterBloomfield bellsouth net>

    Old glib-genmarshal has no --output option
    
    Thanks to Jack for the report
    <URL:https://mail.gnome.org/archives/balsa-list/2017-November/msg00003.html>
    
        * libbalsa/imap/meson.build: use the 'capture' option of
        customtarget, because the old glib-genmarshal has no --output
        option.
        * libbalsa/meson.build: ditto.
