libxl: fix timer configuration
    
    The current logic around configuring timers in libxl based on
    virDomainDef object is a bit brain dead. Unsupported timers are
    silently ignored and tsc is only recognized if it is the first
    timer specified.
    
    Change the logic to reject unsupported timers and honor the tsc
    timer regardless of its order when multiple timers are specified.
