default to COMPRESSION_GZIP unconditionally.
* gnu/services/base.scm (<guix-configuration>)[log-compression]: Default
to 'gzip.
* doc/guix.texi (Invoking guix-daemon, Base Services): Adjust accordingly.

I think bzip2 compression of the build logs doesn’t buy us much, it
doesn’t play well with ‘guix publish’, and bzip2 is generally rather
uncommon these days—hence this patch.

Thoughts?

I haven't tried it, but the idea and code LGTM.
