tools/revent: improve recording + add prebuilts

Browse Source 
The begining and end of recording timestamps are now stored as part of
the recording. This allows to correctly replay recordings where the
first event occurs some time after the recording started, or the last
event some time before recording ended.

Add pre-built revent binaries for the armeabi and arm64 architectures.
