package/busybox: add patch to fix dependency for IFUPDOWN_UDHCPC_CMD_OPTIONS

Upstream commit a8c696bf09d8151323f6e99348c4bc8989f829c8 makes ifup and
ifdown individually selectable, but forgets to update the dependency to
IFUPDOWN_UDHCPC_CMD_OPTIONS, so it is not selectable anymore.

Add a patch which fixes the dependency by checking for IFUP or IFDOWN,
instead of the obsolete IFUPDOWN.

Upstream status: Pending
