Some commands that are called by build scripts are particularly verbose
(ant, dex, readelf). For these commands, the output (when successful)
is not useful (unlike javac, for example). Add an option
(suppress_output) to build_util.CheckCallDie to disable printing of
stdout/stderr when the call is successful.
Also, move remaining build scripts in build/android to
build/android/gyp.

Some build steps, particularly javac, have really loose input rules.
I.e. javac steps are re-built when any input jar changes. Often, this
leads to unnecessary rebuilds of all the following steps.
Other build tools (ninja, goma), will check the contents of the inputs
to a step, and if those inputs haven't changed that tool doesn't
actually re-run the command for creating the output.
This change brings that same benefit to some of the Android python
build scripts. Particularly those that will save a significant amount
of time by adding input content checks.
The checking checks both the input files and the command that will be
run. It compares this against a stored md5 digest. If it has not
changed, then the output does not need to be recreated (though it is
still touched to trigger following steps).

For the component build, it is impractical/impossible to explicitly
list all library dependencies. This list is required (in dependency
order) for several of the apk-building steps.
For now, we will generate this list as follows:
Use readelf to find all transitive dependencies
Topologically sort those dependencies
Once we can expose this information from gyp
(http://crbug.com/2255588), it is straightforward to update this action
to use the gyp-exposed list of libraries.
