sysutils/fcron: fixup default argument promotion

When mode_t is char- or short-like, it will be promoted to the pure
int when it is passed as the variable argument [1], so we should pass
'int' to the va_arg.

I had also eliminated fflush for the stream opened read-only, since
it will always fail and there is no need to flush read-only streams.
