net: ipv6: select DST_CACHE from IPV6_RPL_LWTUNNEL

Browse source

[ Upstream commit 93c21077bb ]

The rpl sr tunnel code contains calls to dst_cache_*() which are
only present when the dst cache is built.
Select DST_CACHE to build the dst cache, similar to other kconfig
options in the same file.
Compiling the rpl sr tunnel without DST_CACHE will lead to linker
errors.
