WifiNative: add wallclock timestamps for packet fate

Packet fate reports are timestampped in a different format than
logcat messages. This makes it hard to correlate packet fate
summaries with other system activity.

Resolve this, by adding wall-clock timestamps to packet fate
summaries.

BUG=28701632
TEST=manual test

Manual test:
- set bullhead to non-GMT timezone
- install build on bullhead
- trigger connection failure
- verify that walltime column is in the right ballpark,
  relative to logcat messages
