tool: fix two more allocator mismatches

memory allocated by libcurl (curl_maprintf) must be freed with
curl_free(), and memory allocated by the tool (curlx_strdup via
findfile) must be freed with curlx_free().

- tool_cfgable: ech_config is allocated with curl_maprintf, free it
  with curl_free() instead of tool_safefree()
- config2setopts: known hosts from findfile() is allocated with
  curlx_strdup, free it with curlx_free() instead of curl_free()
