[Buildroot] [PATCH] package/network-manager: support libnss instead of gnutls

[John Keeping]

NetworkManager supports compiling against either NSS or GnuTLS and in
fact upstream defaults to NSS if both are available and no choice is
specified.  Providing a choice can shrink images slightly if some other
package is already pulling in NSS but GnuTLS is not otherwise required.

Since a crypto provider is required and to maintain backwards
compatibility, select GnuTLS when NSS is not selected.

In keeping with the upstream default, choose NSS when both libraries are
available.
