test-stat-time, test-utimens: improve portability
ext4 on an alpha system has a quantization of about 10 ms but
a resolution of 1ns; utimecmp does not know about quantization,
so tests were failing when comparing timestamps that fall
within the same quantization window. Add strategic usleeps
throughout to minimize this issue, whether or not we later
improve utimecmp to account for quantization.
Windows (and hence cygwin) is documented as having a default
clock quantization of 15.25 milliseconds (although it can be
reduced to 1 millisecond); file timestamps are quantized to this
boundary even though more accurate timing can be obtained.
However, this means that 15 milliseconds is too short for any
test that wants to guarantee crossing a file timestamp boundary.
Cygwin, however, still has bugs where clock_gettime can lag
behind file timestamps, which is not fixed by this patch.
Solaris 9 with NFS exposed the same problem for futimes that was
previously fixed for utimes on Solaris 8, where futimens(f,NULL)
uses a different time source than futimes(,{,UTIME_NOW}).

test-stat-time: speed up execution
Eight seconds was painfully long.

(test_mtime, test_ctime, test_birthtime): Allow for subsecond
execution.
