Changes to linux.py for setup module to return more relevant information for s390

[agilleyrh]

Summary

On S390 systems, gather_facts return "NA" due to not have /proc/sys entries and dmidecode not being available.

I did not have permission to do a pull request but below is a snippet that might get this in the right direction, I am not a python person so this will likely need some refinement.

linux.py.txt

Add the following after line 407:

            else:
                # Open the /proc/cpuinfo file
                with open('/proc/cpuinfo', 'r') as file:
                    # Read the content of the file
                    content = file.readlines()
                    # Search for "S390" in each line
                    for line in content:
                        if "S390" in line:
                            found_s390 = True
                            break
                # Register "IBM/S390" as 'system_vendor' if found
                if found_s390:
                    system_vendor = "IBM/S390"

I'm also looking at /proc/sysinfo:

sysinfo...

Manufacturer:         IBM
Type:                 8561
LIC Identifier:       xxxxxxx
Model:                400              LT1
Sequence Code:        00000000000xxxxx

• https://www.ibm.com/docs/en/linux-on-z?topic=tasks-find-machine-serial

To clarify Manufacturer would be used as system_vendor, Type for product_version, Sequence Code as product_serial with leading 0s stripped. This doesn't cover product_name however, which is usually an friendly name for product_version, so maybe we just duplicate.
