Require hslua-2.2.1, unless lua53 flag is set.

This fixes a problem where the encoding used for Lua filenames would
sometimes mismatch the encoding used by the OS. The file wasn't found
when that happened, for example with an umlaut-containing filename on
Windows. The change ensures that all characters of available in the
default locale can be used in the filename.
