*printf: fix for BeOS

[Bruno Haible]

The snprintf function on BeOS produces no output if the specified size is
>= 0x3000000. Since gnulib's sprintf.c passed a size of 0x7fffffff, it
fully hits this bug.

The workaround is to use the native sprintf instead.

        * lib/vasnprintf.c (USE_SNPRINTF): Define to 0 on BeOS.
