Use CMAKE_CXX_LIBRARY_ARCHITECTURE to detect x86

Bug: https://bugs.webkit.org/show_bug.cgi?id=172799

When building for x86 in a x86_64 host (e.g. with pbuilder) CMake
will set CMAKE_SYSTEM_PROCESSOR to x86_64, and WebKit will assume
that it's a 64-bit build. Let's use the C++ compiler architecture as
a temporary solution to detect x86 correctly.
