amd64: reduce header pollution in _stdint.h

Browse Source 
In 38d1ac34ff SIGATOMIC_{MIN,MAX} were
defined in terms of LONG_{MIN,MAX}.  Later, they were switched to
__LONG_{MIN,MAX} in 78fe75bc28 where an
include of machine/_limits.h was added.  Switch to using fixed width
INT64_{MIN,MAX} and remove the header pollution.

No functional change.
