post_build_ninja_summary.py gives a summary of a ninja build. It can be
run standalone or it can be run automatically by autoninja. This CL
updates the Python script and the autoninja bash script to make this
work on Linux. This includes removing a zero-value assert, and ensuring
that .so files get categorized as such.

Using goma requires the developer to remember which build directories
use goma and which don't so that they can pass an appropriate -j number.
Getting this wrong makes builds slower, either by under utilizing
resources or by causing a self-inflicted DOS attack. Usage:
autoninja -C out/debug
autoninja looks at the settings for the specified build directory and
then selects either -j num_cores*20 or no -j flag based on the
use_goma setting.
You can set the NINJA_CORE_MULTIPLIER variable to change from the
default 20* multiplier. You can also use NINJA_CORE_ADDITION if you
want non-goma builds to specify -j with an offset to the number of
cores, such as this Linux command:
NINJA_CORE_ADDITION=-2 autoninja -C out/release base
This will tell autoninja to pass -j to ninja with num_cores-2 as the
parameter.
On Windows you can have a ninja.bat file (ahead of ninja on the path)
such that autoninja will automatically be used. It should contain this:
@call autoninja.bat %*
