uucore: remove redundant setup_localization call in help template

[ChrisDryden]

Surprisingly I think that this line here is one of the biggest contributors to the flakiness in the valgrind GNU tests. When I look at the memory allocations when shuf is run, this line here is a duplicated call to setup_localization that doubles the amount of allocations for the loading of the fluent files and by removing it the time it takes to load valgrind reduces by 50%.

The best long term fix here would be to implement lazy loading for the translations to only load the translations when they're needed, but hopefully this will increase the stability of the GNU tests for now and should bring some major memory and performance benefits to every utility call.

GNU testsuite comparison:

GNU test failed: tests/misc/io-errors. tests/misc/io-errors is passing on 'main'. Maybe you have to rebase?
GNU test failed: tests/pr/bounded-memory. tests/pr/bounded-memory is passing on 'main'. Maybe you have to rebase?
Congrats! The gnu test tests/factor/t36 is no longer failing!
Note: The gnu test tests/tail/tail-n0f is now being skipped but was previously passing.
Congrats! The gnu test tests/printf/printf-surprise is now passing!
