Automake and autoconf are impossible to fully understand and Meson now provides
everything we need for a much smaller, faster, and more understandable build.

This downloads the latest version of the firmware and applies it to any
matching hardware. e.g.
$ fwupdmgr update
Downloading 1.2.3 for ColorHug...
Updating 1.2.3 on ColorHug...
* Loading firmware
* Decompressing firmware
* Restarting device
* Writing firmware to device
* Verifying firmware from device
* Restarting device
Done!
It seems a little odd to call it 'Update' when it's being used for downgrading
and reinstalling as well.
As we're making things simpler, just use a single 'install' action in fwupdmgr
rather than 'install', 'update-online', 'update-offline'. We can use the flags
and fallbacks to do the right thing in all cases, and make the typical case
(installing a local file to any matching hardware) simple.
