There is following error when compiling applications using http_client:
/zephyr/include/net/http_client.h:157:24: error: field 'work' has \
incomplete type
157 | struct k_delayed_work work;
| ^~~~
/zephyr/include/net/http_client.h:177:2: error: unknown type name \
'k_timeout_t'
177 | k_timeout_t timeout;
| ^~~~~~~~~~~
Fix that by adding missing kernel.h include statement in http_client.h.
