The # Source: header can point to a different repo than what
check_for_gh_release actually queries (e.g. RustDesk uses
lejianwen fork, not official rustdesk repo).
Now parse both app name and source repo directly from the
check_for_gh_release call in the ct script:
check_for_gh_release "appname" "owner/repo"
Also fix $HOME/.appname path expansion in pct exec context.
