The `--verbose` output for getting BIOS setting info is very noisy
on Lenovo systems due to a mismatch for the driver behavior and
kernel API.
Hide most of it behind an optional environment variable
`FWUPD_BIOS_SETTING_VERBOSE`.
This allows us to load sets of different host security attributes
for testing the various front end tools we have now. e.g.
sudo FWUPD_HOST_EMULATE=thinkpad-p1-iommu.json.gz fwupd
or, using a non-compressed absolute path:
sudo FWUPD_HOST_EMULATE=/tmp/test/thinkpad-p1-iommu.json fwupd
Data can be created with `./contrib/generate-emulation.py file.json`
and then can be manually modified if required. Running the script on
a file that already exists will just strip out any unneeded data, as
well as piping content into it using stdin.
As a precaution, the org.fwupd.hsi.HostEmulation attribute is added
so we do not ask the user to upload the HSI report. It also allows
the LVFS to ignore any HSI reports with this attribute for clients
that upload HSI reports regardless.

Using `sudo FWUPD_PROFILE=10 ./src/fwupd --verbose` will print a
dump of startup times onto the console so that we can debug which
plugin is slowing down system startup. For example:
../src/fu-engine.c:5409:plugins-coldplug [108.55ms]:
../plugins/amt/fu-plugin-amt.c:437:amt [27.14ms]:
:create-context [12.66ms]
:get-version [8.44ms]
:add-device [3.95ms]
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`
