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).
[Peter: add comment with reference to rfc3359/option 119 for clarity]
