    mesa: Fix build with vulkan on non-x86
    
    The intel vulkan driver requires libdrm-intel: Only enable it when
    building for x86 or x86-64 similar to DRI drivers.
    
    Building on non-x86* with vulkan leads to "--with-vulkan-drivers= ":
    this is interpreted correctly by the build system.
