[sonic-config-engine] Generate expected output with different cable len (#11092)

Browse Source 
Why I did it
To address internal build failures where the cable len for some of the skus is set to 300m for all tiers.

How I did it
For the buffers test, generate a new output file based off the original expected output with CABLE_LENGTH table updated to use 300m. In the comparison logic, compare against each of the expected output files and if any matches, the testcase is set to pass
