This change removes an outdated Hong Kong HSBCNet module that had already been cleared out internally but still existed as an empty leftover file. It helps keep the codebase clean and avoids confusion about a module that is no longer in use.

The contents of this file were previously deleted, but the file itself 
was missed, leaving a dead l10n_hk_hsbcnet module in 19.4. This commit 
removes the file entirely to clean it up.
