Don't attempt to deflate when compression level is 0

soong_zip -L 0 would attempt to compress with deflate at compression
level 0, then pick store instead of deflate because the overhead of
deflate would always make it larger than the uncompressed size.  Just
use store instead.

Test: m checkbuild
