Reviewed by Carlos Garcia Campos.

Implement functions used by Skia to handle memory allocations in terms
of WTF::fastMalloc() and friends.

* Source/ThirdParty/skia/CMakeLists.txt: Build the fastMalloc allocator
instead of the system-wide one when USE_SYSTEM_MALLOC is disabled.
* Source/WebCore/platform/graphics/skia/ImageBufferSkiaUnacceleratedBackend.cpp:
(WebCore::ImageBufferSkiaUnacceleratedBackend::create): Remove FIXME
comment, allocations done by Skia now go through bmalloc/fastMalloc.
* Source/WebCore/platform/skia/SkiaAllocatorFastMalloc.cpp: Added.
(sk_abort_no_print):
(sk_out_of_memory):
(sk_free):
(sk_realloc_throw):
(sk_malloc_flags):
(sk_malloc_size):
* Tools/Scripts/webkitpy/style/checker.py: Ignore lints for include
headers and underscores in identifiers for SkiaAllocatorFastMalloc.cpp
* Tools/ImageDiff/Skia.cmake: Add logic to avoid linking ImageDiff to
WTF when Skia has the bmalloc/fastMalloc allocator support built.
