    kernel/hack-5.4: make UDP tunneling user-selectable
    
    UDP tunneling support isn't user-selectable, but it's required by WireGuard
    which is, for the time being, an out-of-tree module. We currently work around
    this issue by selecting an unrelated module which depends on UDP tunnelling
    (VXLAN). This is inconvenient, as it implies this unrelated module needs to be
    built-in when doing a monolithic build.
    
    Fix this inconvenience by making UDP tunneling user-selectable in the kernel
    configuration.
