fwupd 1.7.8

[Richard Hughes]

Hi all,

I've tagged a new 1.7.x release, and this branch is what's destined
for RHEL 8. My plan for Fedora and RHEL 9 is to include the 1.8.x
versions, if that helps anybody decide on what to ship.

This release fixes the following bugs:
* Add the bootloader VID/PID used for the first batch of ColorHug devices
* Also check for os-release in SYSCONFDIR
* Export the version lowest raw value correctly
* Fix a Wacom timeout when parsing very corrupt firmware
* Fix Genesys device enumeration failure by not claiming the interface
* Hardcode the Redfish filedata name to firmware.bin
* Install D-Bus introspection data even if introspection is disabled
* Only set the flashrom BIOS size if not already quirked
* Read the SynapticsMST firmware size in a more safe way
* Restart the BMC after installing BCM updates

This release adds support for the following hardware:
* More pixart-rf devices
* More SPIT pccam devices
* Some FlatFrog devices
