libport:Added port_download_src function

This function is to superceed the pkg_download_src function, as that one
is a bit of a misnomer. This one is also simpler and, per the name, it
now only performs one task: downloading source files. The superceeded
function pkg_download_src also handled extraction into the temporary
packaging location, which was an overstep.
