The previous commit added a means to generating the completion scripts
and this one plugs that into the build system.
A new build option 'install_completions' has been introduced. Set to
'True' by default.
Completions for bash and fish use pkg-config for getting the preferred
install locations for the completions. If the packages are not
available, fallbacks are in-place.
The 'completion' subdir has been kept to work around the ideology of
Meson that does not allow creating/outputing files in subdirectories nor
using the output of custom_target() in install_data().

Commit 6c86cabbe5 changed the command line interface to behave
a lot similar to that of github.com/coreos/toolbox, which makes things
easier for those switching over from it.
However, it makes things confusing for the vast majority of users who
have never used coreos/toolbox. The Toolbox CLI aims to be friendly to
new users by being self-documenting and offering a smooth onboarding
experience. It's jarring to new users when 'toolbox', without any
commands specified, suggests that it needs to perform a big download.
It's difficult to document two different sets of CLIs, and if the
manuals don't mention the second behaviour, then it just leaves the
users even more confused.
Hence, it will be good to keep the migration path for coreos/toolbox
behind a build-time option, so that only those OS distributors who
truly need it may enable it without impacting others. Fortunately,
coreos/toolbox doesn't have any manuals, which means that there's no
need to conditionalize the documentation.
This commit merely adds the build-time option. Subsequent commits will
use this to actually conditionalize the code.

When installing to a non-system-wide prefix as a non-root user, the
tmpfilesdir path defined by systemd might not be accessible. Overriding
the path helps to prevent the installation from failing.
