qcom-base.inc: enable tarballs as additional image format

Upstream OE changed the defaults, so the original stanza prevented all
types of tarballs. Enable `tar.gz` to be able to populate external media
like microSD cards a bit easier.

Gzip has been picked over xz because of its speed, both in compression
as in decompression. With `pigz` installed it scales linearly with the
number of CPU cores, removing it as the bottleneck.
