Update system_needs_reboot to use perl call to check kernel boot/running version.

whmapi1 system_needs_reboot can currently return the wrong kernel running_version information inside an AlmaLinux 8 LXC. (It returns the correct information inside CentOS 6 and 7 LXCs.)

As a cPanel System Administrator, I would like it to incorporate a perl call (example in Refs:) such that it returns the correct kernel running_version. This will benefit everyone who uses whmapi1 system_needs_reboot, as API1 won’t be returning wrong information.

Personally this is of high importance as it’s the API I use to trigger email alerts when a server needs to be rebooted. I expect many (most?) developer centric cPanel System Administrator use the same call for similar server automation.

CentOS 7 will reach EOL June 30, 2024. AlmaLinux 8 (EOL 2029) is the suggested replacement.
