The NSS crypto backend requires a special option now, without it
configure errors out with:

configure: error: NSS use must be confirmed using --with-nss-deprecated. NSS support will be dropped from curl in August 2022. See docs/DEPRECATE.md

Since it will be removed entirely soon anyway, and since this version
doesn't fix any CVEs so doesn't need to be backported to stable
branches, drop the NSS option entirely.

Since NSS is going to be removed soon, drop the --without-nss as well.
It is never going to be enabled automatically.
