webkitgtk: fix compiling for 32-bit Arm

When compiling for 32-bit Arm target, the compilation fails with the
following error:

| .../webkitgtk/2.48.5/sources/webkitgtk-2.48.5/Source/JavaScriptCore/offlineasm/ast.rb:1004:in 'Instruction#lowerDefault': Unhandled opcode addq at WebAssembly.asm:739 (due to WebAssembly.asm:739) (LoweringError)

Add backported patch to fix this error.
