Generate bench/Android.mk from gyp.

Generate bench/Android.mk from gyp.

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

bench/DeferredSurfaceCopyBench.cpp:
Include GrRenderTarget last, so SK_SUPPORT_GPU will be set properly.

bench/ResultsWriter.h:
bench/benchmain.cpp:
Remove JSONResultsWriter when SK_BUILD_JSON_WRITER is not defined,
which is the case for the Android framework build.

gyp/bench.gyp:
Depend on skia and cutils (for android_atomic_inc etc).

gyp/common_conditions.gypi:
Define SK_BUILD_JSON_WRITER when skia_build_json_writer is set.

gyp/common_variables.gypi:
Add a flag for skia_build_json_writer, and set it only when
skia_android_framework is not set.

gyp/jsoncpp.gyp:
Do not build jsoncpp when skia_build_json_writer is not defined.
include/utils/SkJSONCPP.h:
Do not include json headers when SK_BUILD_JSON_WRITER is not defined.

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

platform_tools/android/gyp_gen/gypd_parser.py:
Skip dest_dir when checking for include_dirs.

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

platform_tools/android/gyp_gen/tool_makefile_writer.py:
Add a parameter for putting the binary into /data/local/tmp.
