The 24.05 update for KDE Connect moved the kdeconnectd binary from
`/libexec` to `/bin`, so this fix will check the version of the
package used and set the path accordingly.
The PR #5299[0] actually adds the requirement on "tray.target" for the
kdeconnect service, when kdeconnect-indicator is set to true. What it
should do is add the requirement directly to the latter. This commit
fixes it.
