Fix - just use two arguments without buflen

On VxWorks, strerror_r() does not take a third argument.

This patch just uses the two arguments and *hopes* that we have enough space
allocated.  There does not appear to be a way to avoid the potential for a
buffer overflow.

At least we can pretty safety assume that the system error messages won't be
overly long.

The alternative is to fall back on strerror(), but that has reentrancy issues.
