gnu: mercurial: Add package and rename former to mercurial/pinned.

Mercurial currently has CVEs. IMHO, it's unsafe to carry them around
in a profile.  However, updating mercurial potential leads to a lot of
rebuilds and I don't want to tackle this right now.

As for other packages, the way forward is to add a variant of the
package only used for hg-fetch, here mercurial/pinned.

* gnu/packages/version-control.scm
(mercurial-check-phase): Add helper variable.
(mercurial): Update to 7.1.
[arguments]: Use gexps.
<#:phases>: Refresh them. Add phase 'add-install-to-pythonpath for
running tests. Run tests after install. Add phase 'configure-check.
<#:imported-modules, #:modules>: Add them for
'add-install-for-pythonpath.k
[native-inputs]: Remove python-nose. Add python-setuptools-next,
python-setuptools-scm-next.
(mercurial/pinned): Inherit from mercurial, but build the exact same
derivation as the previous mercurial variable.

* guix/hg-download.scm (hg-package): Use mercurial/pinned.
