Switch python indentation from 2-space to 4-space (#2299)

pep8 specifies 4 space indentation.  The use of 2 spaces is, I believe
a historical anomaly where certain large organizations such as google
chose 2 over 4 and have yet to make the switch.

Since there isn't too much code in binaryen today it seems reasonable to
make the switch.
