That bin directory should no longer be there

...at least since 7a08bfea "tdf#122244 Put
InfoPlist.strings files at correct places on macOS", though it wasn't under
Contents/ at least as of lately, anyway.

The code to remove it had been added with
f345a2c5 "We don't want those
bin/InfoPlist_*.zip files in the app bundle".  I don't know how to do a
--enable-macosx-code-signing build on macOS to verify that it can indeed be
removed, though.
