Linux: Adjust gedents64 buffer size to int range [BZ #24740]
The kernel interface uses type unsigned int, but there is an
internal conversion to int, so INT_MAX is the correct limit.
Part of the buffer will always be unused, but this is not a
problem. Such huge buffers do not occur in practice anyway.
