This allows libseat users to e.g. advise people to chmod a+s the
executable if libseat is built with the builtin backend.

While bumping the Meson version, adjust the scdoc logic to avoid
the following warnings:

    WARNING: Project targeting '>=0.56.0' but tried to use feature deprecated since '0.56.0': Dependency.get_pkgconfig_variable. use Dependency.get_variable(pkgconfig : ...) instead
    WARNING: Project targeting '>=0.56.0' but tried to use feature deprecated since '0.55.0': ExternalProgram.path. use ExternalProgram.full_path() instead
---

There is still one warning about meson.build_root(), but we can't get
rid of it until [1] is available.

Setting auto_features=disabled is supposed to disable all optional
dependencies. Since we aren't using a feature option here, we need
to manually add logic to disable logind in this case.

This bumps the required Meson version to 0.56.0, released last
October.

Is there a reason why this is not enabled on all architectures? Is it
only available on amd64?

Ah, one more small thing: maybe the commit message can be improved a bit.
Maybe something like "openbsd: add current"?

The mercurial package has been moved to community.

These features don't have any dependencies, so "auto" doesn't make
sense.
