ACPICA: utilities: fix sprintf()
This contains changes for the following ACPICA commit ID's:
8f99a6ccd3b8e5c3d3d68c53fdbb054c2477eeb4
d30647af53abd334cbcf6362387464ea647bac9e
d3c5fb4cf5b2880d789c987eb847fc3de3774abc
On 32-bit, the provided sprintf() is non-functional: with a size of
ACPI_UINT32_MAX, String + Size will wrap, meaning End < Start, and
acpi_ut_bound_string_output() will never output anything as a result.
The symptom we saw of this was acpixtract failing to output anything.
