fix(linux): address PR AprilNEA#173 review comments

- install.sh: rewrite ExecStart in the systemd unit via sed so the
  installed service always points to $BINDIR/openlogi-agent, not the
  hardcoded /usr/bin path (which mismatches the default /usr/local prefix)
- uninstall.sh: add udevadm trigger after reload so hidraw and uinput
  nodes lose the uaccess tag immediately, not only after re-plug/reboot
