Use SkGraphics::Init to output to stdout (Android)

Use SkGraphics::Init to output to stdout (Android)

SkGraphics::Init is only used on Android when running our tools,
which is exactly the place where we want to see output sent to
stdout in addition to logcat.

Alternate approach for getting stdout from Android tests.

https://codereview.chromium.org/790203002/diff/1/src/core/SkGraphics.cpp
File src/core/SkGraphics.cpp (right):

https://codereview.chromium.org/790203002/diff/1/src/core/SkGraphics.cpp#newc...
src/core/SkGraphics.cpp:74: AndroidSkDebugToStdOut(true);
We can also set this back to false in Term(). (This would be a change in
behavior though.)

File include/core/SkGraphics.h (right):

https://codereview.chromium.org/790203002/diff/1/include/core/SkGraphics.h#ne...
include/core/SkGraphics.h:20: *  On Android, sends output to stdout in addition
to logcat.
Downside to this approach is that if someone is using SkGraphics::Init() but
they do *not* want stdout on Android, they are stuck with it.

this approach means we set it to true on non-testing builds (e.g. libskia.so in
the framework) which we don't want to do.

Oops. I didn't think the framework called Init, but you are correct; they do.
