lib/tests: Pass int to va_arg instead of char.

Browse source 
* lib/tests/scaffold/70-stdarg.c (stdarg1, stdarg2, stdarg3): Pass int
to va_arg instead of char to avoid gcc trap "warning: 'char’ is promoted
to ‘int’ when passed through ‘...’ [enabled by default] (so you should
pass ‘int’ not ‘char’ to ‘va_arg’) if this code is reached, the program
will abort".
