scripts/savecore: Report nicely when there's no core dump

Browse source 
When savecore can't find a core dump, it reports something like

    ls: cannot access core.*: No such file or directory

to stderr, and fails.  If privlog is set, it also mails out a "Could
not save core dump" note.

Suppress the error message, and mail out "Could not find core dump to
save" instead.
