Use the gitlab CI tokens as files, not environment variables
meson drops the whole environment into testlog.txt
- that includes the various gitlab CI tokens that we need to access the registry. In our case the two personal tokens and the pipeline trigger for the wayland website (all revoked by now).
Fix this by making both a file in the environment and then loading them from the file.
- the registry tokens must be netrc files
- the wayland web token can be loaded by curl
The curl bit is untested as yet, need a new token first.
