Subject: [PATCH] gluon-status-page: use UCI + iwinfo to get channel
 information

The network.wireless status ubus call only returns the configured
channel from UCI, breaking the status page in outdoor mode, where the
configuration contains 'auto' instead of a number.

Fixes: 0d3fa6b59be7 ("gluon-status-page: use ubus to get radio channels")
Closes #2336
