xbps-repo: changed the 'sync' target to update from all registered

remote repositories, so remove its argument.

xbps_sync_repository_pkg_index:
 - create the local repo dir in XBPS_META_PATH.
 - also add the uri scheme (http://, https://, ftp://) in the created
   local directory and subst ':' also with an underscore.
 - do not create local repo directories unless the download pkg-index
   plist file is verified to be fetched correctly.

xbps_check_is_repo_string_remote:
  New function to check if a repo string is a remote repository, use
  it in all places where it was used before.
