description:
network: Update rtsol options

- Use "-6" instead of "--noipv4" as it seems more appropriate based on
  the dhcpcd(8) manual page.
- Remove "-f /dev/null" as it seems unnecessary with "-6".
- Remove "--persistent" as it is in the default /etc/dhcpcd.conf,
  and this way the user can change it, if they would like to (either
  through dhcpcd_flags or by editing /etc/dhcpcd.conf).

The "-b" (or "--background") option is needed to avoid a timeout error
message (and a delay in booting), so it is still left in place.
