package/swupdate: Update to version 2018.11

Update to version 2018.11 to resolve the following build failure:

corelib/channel_curl.c: In function ‘channel_map_curl_error’:
corelib/channel_curl.c:298:2: error: duplicate case value
  case CURLE_SSL_CACERT:
  ^
corelib/channel_curl.c:297:2: error: previously used here
  case CURLE_PEER_FAILED_VERIFICATION:
  ^

when building with CONFIG_DOWNLOAD=y. This issue is happening since
the libcurl bump to 7.62.0.
