[PATCH v3 02/74] qapi/gen: fix _module_basename for multi-dash 'what' parameters

The re.sub() call replaces every hyphen in 'what' with the system module
infix. This produces broken filenames for multi-hyphen names (e.g.
'qapi-type-infos' becomes 'qapi-builtin-type-builtin-infos').

Add count=1 so only the first hyphen is replaced.
