user/clucene: tell check to use $builddir/tmp instead of tmp

If we use /tmp (the default), successive runs of check will usually fail
because /tmp is not cleared on each run, and clucene is not smart enough
to delete its test files on its own, so a whole bunch of tests will
fail. Instead, tell it to use $builddir/tmp, which we can safely clear
each time we run check.
