[archiso] Cleanup: pxe_curl: Remove download-iso-loopback support.

This was the first implementation that downloads the complete ISO,
but now we have the posibility of download only needed *.sfs files.

** hooks/archiso_pxe_curl
* archiso_curl_url= Set an HTTP/FTP URL of an ISO file (first form),
or a path (must end with /) where ${archisobasedir}
is found with all *.sfs files (second form).
In the IP part if ${pxeserver} is used, PXE IP will be used.
* archiso_curl_url= Set an HTTP/FTP URL (must end with /) where ${archisobasedir}
is found with all *.sfs files.
In the IP/domain part if ${pxeserver} is used, use PXE IP.
Default: (unset)
* curlspace_size= Set the size of tmpfs of "curlspace" where the specified
ISO image or *.sfs files are downloaded.
