lib/vsprintf: Use EXPORT_SYMBOL_IF_KUNIT() to export symbols

Browse Source 
Replace EXPORT_SYMBOL_FOR_MODULES() with EXPORT_SYMBOL_IF_KUNIT()
to mark the symbols as visible only if CONFIG_KUNIT is enabled.

Kunit test should import the namespace EXPORTED_FOR_KUNIT_TESTING to
use these marked symbols. This is the standard way for all KUnit
tests.
