    mini-os: allow 4096 event channels for 64-bit mini-os
    
    Limiting the number of event channels to 1024 is fine for 32-bit
    builds, but not for 64-bit ones. This might be a problem when using
    Xenstore-stubdom as the number of domains which can be supported is
    then limited to a little bit more than 1000.
    
    So raise the number of event channels to 4096 in 64-bit builds.
