[PATCH] odhcp6c: add "verbose" option

[Mark Mentovai]

odhcp6c logs messages related to its activity when invoked with -v, but
there is no way to configure this from within OpenWrt. This adds a UCI
option to turn on odhcp6c logging, disabled by default. To enable, set,
for example, network.wan6.verbose = 1.
