Fix for hsbp-manager service crash

When hsbp-manager FRU is corrupted with "Board Mfg" name,
hsbp-manager.service is crashing while extracting Board Mfg from the
FRU and dumping the core.

So add if condition to read when name of the variant contains
exactly string.

Tested:
Verified with corrupted hsbp-manager fru and hsbp-manager.service did
not crash with this change.
