Add PackIt config

[davide125]

So we can get some signal on package builds in Fedora.

[davide125]

/packit build

[packit-as-a-service]

We have requested the builder permissions for the @asahi/packit-builds Copr project.

Please confirm the request on the @asahi/packit-builds Copr project permissions page and retrigger the build by clicking on a Re-run button or with a /packit build pull-request comment (for builds in pull-requests).
