webkit: fix mmu reverse dependency moving it to %_ARCH_SUPPORTS

Because mmu dependency was not propagated move it to
BR2_PACKAGE_WEBKIT_ARCH_SUPPORTS to automatically propagate it.
It can ben moved to BR2_PACKAGE_WEBKIT_ARCH_SUPPORTS because like
target architecture dependencies it doesn't modify the comment string.
