paycheck: fix errors around percentage / formatting of zero sizes
This fixes two problems, both having to do with histogram generation:
* When the total number of elements is zero, paycheck would crash due to
a division by zero; further, even if the crash is fixed (returning,
say, None) the histogram will contain a meaningless value in
parenthesis, which we might as well drop. Both are fixed here.
* When some size (say, bytes) is zero, its formatter
(bytes-to-human-readable) returns None, which shows up as is in the
final report. This should be checked and avoided.
BUG=None
TEST=Crash fixed; None percentage/formatted value omitted.

Update payload library + command-line tool
An initial implementation of a Python module for parsing, checking and
applying a Chrome OS update payload. Comes with a command-line tool
(paycheck.py) for applying such operations on payload files, and a test
script (test_paycheck.sh) for ensuring that the library and tool are
working correctly.
Since update_payload is introduced as a package, we're moving some
previously merged utilities into the package's directory.
(Unit testing for this code will be uploaded on a separate CL; see
chromium-os:39663)
