cdb9e5b odhcpd: improve RFC9096 § 3.5 SLAAC compliance

RFC9096 § 3.5 SLAAC compliance introduces a new config option (odhcpd
piofolder), which may wear out the flash under certain conditions (for
example: ISPs with dynamic IPv6 prefixes which disconnect the clients
every X hours).
Therefore, setting "dhcp.odhcpd.piofolder" to persistent storage in the
router flash is not advisable and should be set to other kinds of
persistent storage such as USBs, SDs, NVMEs...
In order to prevent wearing out the router flash it's set to ephemeral
storage by default (tmp):
  uci set dhcp.odhcpd.piofolder="/tmp/odhcpd-piofolder"
