[tracker/tracker-3.0] ci: Avoid usage of `su` command

[Carlos Garnacho <carlosg src gnome org>]

commit 0970a5137bdb82bedc50776b5c172d30b3580e80

    ci: Avoid usage of `su` command
    
    Adapt to https://gitlab.gnome.org/GNOME/tracker-oci-images/-/merge_requests/28.
    We no longer can (nor need to, really) switch users with `su`. Drop these
    calls, and account for the changes of $CWD in the course of the issued commands.
