ipkg-build: suppress timestamps in gzip headers
When creating control.tar.gz, data.tar.gz and $package.ipk tar compresses them with default gzip options. This includes build timestamps in their gzip headers. By setting the GZIP env variable to -n, gzip no longer embeds them, which is a step towards reproducibility. See also [1] for more detailed motivations.
