build(deps): bump deps/mqtt-c from 0f4c34c to 7a986a6

Notable changes:
- Fix reconnect initialisation (message queue init when buf is NULL)
- Initialise pid_lfsr to zero in mqtt_init_reconnect()
- Avoid detection of use of NULL pointer
- Code quality: const, static, macro parentheses, lint fixes
- Add zig-cc cross-compilation support
