kernel.bbclass: add gzip-native to do_deploy dependencies
When a modules tarball is created during kernel_do_deploy,
the tarball is compressed using gzip, but gzip-native is not
a dependency so the build host's gzip is being used for this.
Using gzip-native will, by default, use pigz instead of
single-threaded gzip, making this task less of a bottleneck
for builds with a large modules package.
