ifupdown: support "source-directory" stanza
Support the "source-directory" stanza from ifupdown[1]. source-directory
will include all files in the named directory. Similar to the Busybox
version of the "source" stanza, this version of source-directory does
not currently support shell wildcards.
We only check that the stanza starts with "source-dir" as ifupdown does[2].
