Link non-vcs sources into $srcdir during extraction

The separation between downloading and extracting for non-vsc sources
was incomplete due to symlinks being made in $srcdir during the download
stage.  Have download_{local,file} just ensure the presence of the files
in $startdir or $SRCDEST (downloading if needed) and then have
extract_file symlink these files into $srcdir.

Also replace "continue" with "return" in extract_file to make it clearer
what is happening.
