checkrestart functionality for Debian and Red Hat Based systems
Identifies services (processes) that are linked against deleted files (for example after downloading an updated
binary of a shared library).
Based on checkrestart script from debian-goodies (written by Matt Zimmerman for the Debian GNU/Linux distribution,
https://packages.debian.org/debian-goodies) and psdel by Sam Morris.

Once a NILRT kernel module is inserted, it can't be rmmod so systems need
rebooting (some modules explicitly ask for reboots even on first install),
hence this functionality of determining if the module state got modified by
testing if depmod was run.

Besides the normal Linux kernel driver interfaces, NILinuxRT-supported hardware features an
extensible, plugin-based device enumeration and configuration interface named "System API".
When an installed package is extending the API it is very hard to know all repercurssions and
actions to be taken, so reboot making sure all drivers are reloaded, hardware reinitialized,
daemons restarted, etc.
Returns:
- True/False depending on if nisysapi.ini got modified/touched
- False if nisysapi.ini does not exist to avoid triggering unnecessary reboots
