Use piOverTwoDouble instead of M_PI_2

Because M_PI_2 is not defined everywhere.
Fixes errors like:
  CXX      Source/WebCore/platform/graphics/freetype/libPlatformGtk_la-FontPlatformDataFreeType.lo
../webkitgtk-2.4.8/Source/WebCore/platform/graphics/freetype/FontPlatformDataFreeType.cpp: In function 'void WebCore::rotateCairoMatrixForVerticalOrientation(cairo_matrix_t*)':
../webkitgtk-2.4.8/Source/WebCore/platform/graphics/freetype/FontPlatformDataFreeType.cpp:123:34: error: 'M_PI_2' was not declared in this scope
     cairo_matrix_rotate(matrix, -M_PI_2);
                                  ^
GNUmakefile:51663: recipe for target 'Source/WebCore/platform/graphics/freetype/libPlatformGtk_la-FontPlatformDataFreeType.lo' failed
