temp-file: Use 64 kB buffer for temporary files.

Generally PSPP uses temporary files because it has a lot of data to
write to them.  The default glibc buffer is only 4 kB.  In my tests
using a 64 kB reduced runtime from 2.5 seconds to 2.0 seconds, but
increasing the buffer to 1 MB had no additional effect, so 64 kB is a
reasonable choice.

Bug #33260.
