fmap.py: pretty print the object by default

Dumping the structure as a single line makes it hard to read.  Format
it for use humans by default and add a --raw option for people who are
using this tool in scripts.

BUG=chromium:982465
TEST=`./fmap.py bin/example.bin` shows human formatted output
TEST=`./fmap.py --raw bin/example.bin` shows one line
