[Bug translator/9941] New: add dwfl_*_report_offline callback for quick pending_interrupts exit

["fche at redhat dot com" <sourceware-bugzilla at sourceware dot org>]

When the filesystem caches are cold, the first stap run can load up
a slew of modules/debuginfo data (even it not really needed: bug #3498).
During this time, the code loops within elfutils for potentially many
seconds, with no opportunity to check for ^C for an early abort.

The predicate function callback for these dwfl functions is currently
unused, but could be a reasonable way to check for pending_interrupts
and return the nearest thing to CB_ABORT.
