README: fix xargs -P example when there are no feeds
Kindof a non-issue but if theres a sfeedrc with no feeds then xargs will still
be executed and give an error. The xargs -r option (GNU extension) fixes this:
From the OpenBSD xargs(1) man page:
"-r Do not run the command if there are no arguments. Normally the
command is executed at least once even if there are no arguments."
Reproducable with the sfeedrc:
feeds() {
true
}
