On U+ require config_networkWakeupPacketMark/Mask to be 0x80000000

See system/netd/include/Fwmark.h which reserves the bottom 21 bits
of skb->mark for netid, etc... so out of necessity these have to be
in the top 11 bits.

In practice the only values that really make sense are either:
  mark == mask == 0 (disabled)
or (mark == mask) being one of the top 11 available bits, for example:
  mark == mask == 0x80000000 (enabled, using top-most bit)
(only a single bit makes sense, as this is really just a boolean signal,
 and only the topmost is known to be used on any real devices)

Let's just force the use of 0x80000000 for ecosystem consistency.
