busybox: Support option 119 in udhcpc default script.
* package/busybox/udhcpc.script: Use $search instead of $domain if that is defined. Note that for this to work, not only has CONFIG_FEATURE_UDHCP_RFC3397 be enabled in Busybox' configuration but also the option has to be requested using the "-O search" command-line option (one can set it in CONFIG_IFUPDOWN_UDHCPC_CMD_OPTIONS, for instance).
