Generate gm/Android.mk, minus JSON.

When running gyp_to_android.py, generate the makefile for gm.

For now, remove json functionality and do not depend on json. This
allows us to build and run until solving skbug.com/2448.

gm/gm_expectations.cpp:
gm/gm_expectations.h:
gm/gmmain.cpp:
Remove all json functionality when SK_BUILD_JSON_WRITER is not defined.
This flag is not defined when SK_BUILD_FOR_ANDROID is defined.

gyp/gm.gyp:
Depend on skia and cutils.

platform_tools/android/bin/gyp_to_android.py:
Generate gm/Android.mk.

platform_tools/android/gyp_gen/makefile_writer.py:
Build gm/Android.mk when building external/skia.

Depends on https://codereview.chromium.org/282053002/
