I am currently unable to attach a build log, bugzilla errors out with "Internal Server Error".
I've found the cause of the error, though.

in pkg_setup(), vala_setup needs to be called to setup the vala environment. In 1.7.6. which was EAPI 7, vala.eclass had vala_src_prepare which just called vala_setup, but that went away when 1.7.7 changed to EAPI 8. In the log file the following lines also appear:
>>> Preparing source in /var/tmp/portage/sys-apps/fwupd-1.7.7/work/fwupd-1.7.7 ...
/var/tmp/portage/sys-apps/fwupd-1.7.7/temp/environment: line 3185: vala_src_prepare: command not found
>>> Source prepared.

So the call to vala_src_prepare should also be removed.
