scripts/feeds: fix 'src-include' directive

Commit 775b70f8d5df renamed parse_file() parameters without
updating the recursive call. This broke parsing of any feeds.conf
using 'src-include'.

 $ scripts/feeds update -a
 Can't use string ("defaults") as a HASH ref while "strict refs" in use at scripts/feeds line 63, <$fh> line 1.
