Improve printf handling of size_t args

The %*s format takes two arguments, a precision length/width and
an actual string; the length is specified as a signed integer.
The size_t length field of the gss_buffer_desc type is an unsigned
type, which must be cast or otherwise converted to a signed type
to match the format string expectations.
I do not think that the length will approach SIZE_T_MAX in practice,
due to buffer constraints, so do not include handling for the
edge case.

There is a '%zu' format string for printing size_ts, but it is not
available everywhere (e.g., AIX).  Instead, use the
unsigned long long abomination.
