This adds support for optionally using a UNIX domain socket where a
D-Bus daemon may not be running.
To use this, launch the daemon and clients with something like
`FWUPD_DBUS_SOCKET=/var/run/fwupd.sock fwupdmgr get-devices`
This allows us to override the location we load data files from, which
allows us to do more kinds of installed tests in the future.
Also, move the global data/tests content into the place that it is used
as it was getting impossible to manage.
On Alterlake and newer hardware the Platform Health Assessment Record
data can be used by the IHV to debug why a specific capsule update
failed. Any custom firmware loaded by the OEM can be identified and
used to further debug the root cause.
In some CI infrastructures other devices show up and so the webcam
is not automatically picked.

Requiring colord to be built before fwupd makes it hard to build packages.
The HID-based flashing protocol is stable and documented, so there's no need
to use an external library for this now.
The previous fix (db6ed9ede3) didn't
do a good enough job and autopkgtest was still failing on another
individual test.
This makes sure that stderr will never conflict with autopkgtest
in the future.
The autopkgtest test cases in Debian and Ubuntu are failing due to
output present in stderr.
fwupdmgr behavior however is that it's expected that this test should
show output on stderr for this item.
Previously, the various install paths were obtained using get_option
as needed.
This patch unifies the directory selection inside the top-level meson
file as requested in https://github.com/hughsie/colord/pull/62.
This allows us to flash hardware like the Retrode and other devices using chips
like the AT90USB1287.
The test files can be re-generated using the sample code found here:
https://github.com/hughsie/fwupd-test-firmware and are designed
to be used on the AT90USBKEY2 development board.
