    Fix <machine/varargs.h> use cases.
    
    First varargs.h depended on namespace pollution to provide typdef of __va_list
    to declare va_list. Usually thorugh sys/systm.h including sys/stdarg.h
    
    So short-circuit directly to compiler builtin in case of __GNUC__
    
    Also remove machine/varargs.h usage from other kernel sources:
      sys/kern/kern_dsched.c: Not needed (just 3 dummy functions)
    
      sys/dev/misc/tbridge/tbridge.c: Both use just __va_smth variants
      sys/kern/subr_taskqueue.c:      and get those through sys/systm.h
    
    This leaves all the kernel code using <stdarg.h> variant consistently.

Summary of changes:
 sys/cpu/x86_64/include/varargs.h | 2 +-
 sys/dev/misc/tbridge/tbridge.c   | 1 -
 sys/kern/kern_dsched.c           | 1 -
 sys/kern/subr_taskqueue.c        | 1 -
