fs/config, lib/terminal: use golang.org/x/term

golang.org/x/crypto/ssh/terminal is deprecated in favor of
golang.org/x/term, see https://pkg.go.dev/golang.org/x/crypto/ssh/terminal

The latter also supports ReadPassword on solaris, so enable the
respective functionality in fs/config for solaris as well.
