With this change, each substitute occupies a single line of
output (instead of two) when using '-v1', the default for 'guix package'
& co.

* guix/status.scm (print-build-event): Add #:print-urls? and honor it.
(print-build-event/quiet): Pass #:print-urls? #f.
(print-build-event/quiet-with-urls): New procedure.
(logger-for-level): Add case for LEVEL 2.
* doc/guix.texi (Common Build Options): Adjust '--verbosity'
documentation.

The immediate effect is that, with '--verbosity=1', only two lines are
displayed for each substitute, instead of two lines followed by an empty
line.

* guix/scripts/substitute.scm (process-substitution): Emit a single
newline upon completion when PRINT-BUILD-TRACE? is true.

* gnu/packages/julia-xyz.scm (julia-commonsubexpressions)[synopsis]
[description]: Fix Texinfo syntax.

* gnu/packages/gnome.scm: Remove unnecessary #:use-module forms.
In particular, the (guix store) import led to a name clash with 'build'
from (gnu packages build-tools).

* gnu/services/sysctl.scm (sysctl-configuration-sysctl)
(sysctl-configuration-settings): Export.
