dhcp: T3113: bugfix for multiple domain-search entries

While rewriting the code to get_config_dict() in commit 84b7ade286 ("dhcp: T3100:
migrate server configuration to get_config_dict()") a regression was added not
properly joining strings when multiple search-somains had been given.

Wrong: domain-search "domain1, domain2";
Correct: domain-search "domain1", "domain2";
