[Buildroot] [PATCH 4/7] package/domoticz: bump version to 2026.3

[Bernd Kuhls]

Added new dependency jwt-cpp needed since 2025.1:
https://github.com/domoticz/domoticz/commit/b30d9e9436ad428a2cbfd1fbb273461bdbf50a82

Added _EXTRA_DOWNLOAD for libwebem after its split from domoticz:
https://github.com/domoticz/domoticz/commit/7de4834e9959e8a9a21a2b82bb7700ea5af6e618
to avoid fetching git submodules. Use version number from upstream repo:
https://github.com/domoticz/domoticz/tree/2026.3/extern

Raised minimum gcc version because libwebem depends on c++17:
https://github.com/domoticz/libwebem/blob/master/README.md

Removed configure option USE_BUILTIN_MQTT due to its upstream removal:
https://github.com/domoticz/domoticz/commit/be95eec094bf524c1ab011eebcd797d3b19b17fc

Link to libatomic to fix a build error
