stdarg: use sysv varargs when we build with coverity

cov-analysis-linux64-2020.09 is a lot more successful than the older
versions at building, but it still has some... issues.  Among them, it
is of the belief that this:

void
foo(char *fmt, ...)
{
  __builtin_va_list ap;

  __builtin_ms_va_start(ap, fmt); /* <- here */
  ...
}

is an uninitialized use of "ap".

This patch adds defined(__COVERITY__) to the list of criteria for using
sysv va lists, which it has no such confusion about.
