lldpd: remove unneeded quotes and variable quoting

from commit ac771313ebedd2c4bfda8adef47650d45d77c32d

portidsubtype takes 1 of 2 possible keywords which do not need quoting:

         configure lldp portidsubtype ifname | macaddress

The third keyword 'local' is used in the syntax when individual ports
are being defined:

         configure [ports ethX [,…]] lldp portidsubtype local value

When this syntax is used, quoting is useful (see test cases for lldpd).
In the init file, the 'local' syntax is unused.

Tested on 22.03.5
