Add the gzip/gunzip/zcat tests I wrote for toolbox gzip/gunzip/zcat.

Bringing the zlib-based gzip/gunzip/zcat over to toybox is a problem for
another day, but at least the tests are easy...

(These tests pass with TEST_HOST and on the toolbox versions, but the
toybox toys are in pending and very broken.)
