[PATCH v1] env: add w flags for net config in explicit write mode

[Heiko Schocher <hs@nabladev.com>]

From: Adrian Freihofer <adrian.freihofer@siemens.com>

In explicit write access mode (CONFIG_ENV_WRITEABLE_LIST) the
environment variables listed in NET_FLAGS and NET6_FLAGS are
probably intended to be writeable. Therefore add the 'w' flag
to these variables.
