[build] Fix sonic-utilities-data submodule dep (#22917)

Why I did it
The sonic-utilities-data_1.0-1_all.deb target depends on sources from the src/sonic-utilities submodule. However, the cache dependency file does not list this submodule as a dependency. So, when the build cache is used, updates to the src/sonic-utilities submodule pointer do not trigger the necessary rebuild of sonic-utilities-data_1.0-1_all.deb, leading to a stale build output.

How I did it
Updated rules/sonic-utilities-data.dep to include the proper SMDEP rules.

How to verify it
Perform a build with the dpkg cache enabled
Confirm the new output file target/debs/bookworm/sonic-utilities-data_1.0-1_all.deb.smdep is created, containing the submodule dependencies (smdeps)
Archive the target/debs/bookworm/sonic-utilities-data_1.0-1_all.deb output outside the build workspace
Clean the build workspace
Update the src/sonic-utilities submodule pointer to a new commit that contains different source code
Perform another build with the dpkg cache enabled
Extract the previous and current sonic-utilities-data_1.0-1_all.deb outputs. Confirm that the contents of the debian packages are distinct and contain the expected source based on the respective src/sonic-utilities submodule pointers

This is a build bug which silently results in incorrect build outputs when the dpkg cache is used. As such, it should be double committed.
