Create /var/run/reboot-required file

Fix #195

[FrostyX]

RPM available here: https://copr.fedorainfracloud.org/coprs/frostyx/tracer/build/5929476/

[major]

So I tried the code from this PR and I didn't see the file being written. Perhaps I didn't do something correctly.

Output:

You should restart:
  * Some applications using:
      sudo systemctl restart NetworkManager
      sudo systemctl restart auditd
      sudo systemctl restart chronyd
      sudo systemctl restart dbus-broker
      sudo systemctl restart qemu-guest-agent
      sudo systemctl restart sshd
      sudo systemctl restart systemd-journald
      sudo systemctl restart systemd-logind
      sudo systemctl restart systemd-oomd
      sudo systemctl restart systemd-resolved
      sudo systemctl restart systemd-udevd
      sudo systemctl restart systemd-userdbd

  * These applications manually:
      (sd-pam)
      dnf

Additionally, there are:
  - 3 processes requiring restart of your session (i.e. Logging out & Logging in again)
  - 1 processes requiring reboot

For more information run:
    sudo tracer -iat 1684410627.5498843

But no file was written:

[root@tracer-testing ~]# cat /var/run/reboot-required
cat: /var/run/reboot-required: No such file or directory

Nevermind -- an update in F38 clobbered the testing RPM from this change. This works just fine! :partying_face:

[root@tracer-testing ~]# tracer

Tracer says reboot is required

Perfect, thank you for the test.
