[PATCH] tests: avoid split/filter test failure on very low-mem system

[Jim Meyering]

I saw this test fail when run via make -j2 on a low-memory arm-based system,
but not when run in isolation.

 system

* tests/split/filter: Use xz -1 when compressing, to minimize
memory usage.  Otherwise, xz could fail due to insufficient
virtual memory on a system with very little free memory.
