Paul Donald 53252eeb3b lldpd: Implement location parameter 
Previously only partially implemented. After commit
5007f488bb lldp_location was never removed

Now, add the value of lldp_location to the generated config.

The location param has a few syntaxes, so the config acquires the first
usage from the man page: 'address country EU'

Supplementary fix for PR #14193 (this param was included in the original
PR #13018 but the lldp_location fixes were absent from PR #14193).

Tested on 22.03.5, 22.03.6
