keycodes: remove file_id

The file_id thing is used to identify the XkbFile some statement
originally came from. This is needed to avoid spurious warnings; for
example, if you write the same alias twice in a file, that's redundant,
and you'd want a warning about it. However if intentionally override it
from another file, that's fine, and you shouldn't get a warning. So by
comparing the file_id's the needed log verbosity is changed.

However, the file_id mechanism is really not needed, because we already
have that info! Each KeyNamesInfo corresponds to one XkbFile, so if the
conflict occurred while handling that one file -> same_file = true, and
if it occurs while merging two Info's -> same_file = false.
