oem-ibm: Adding entity path correction function

This commit introduces enhancements to rectify entity paths over DBus.
Formerly, the conventional DBus path involved appending an instance
number, such as 'system' becoming 'system1', 'motherboard' becoming
'motherboard1', and 'chassis' becoming 'chassis1'. This function is
designed to align with IBM's specific use case, ensuring the numbering
system adheres appropriately.

Testing:
Unit tests passed
