symbols: remove unneeded recursion form CopySymbolsDef

This function does some funky stuff, which, as far as I can tell, was
needed to support the functionality of giving different keycodes the
same name and thus make them duplicates (MERGE_ALT_FORM). This stuff was
removed as useless in 0765064b3, but this leftover wasn't noticed.
