[nft PATCH] libnftables: Drop symbol nft_bison_have_extended_errors

[Phil Sutter <phil@nwl.cc>]

It was merely used to indicate extended parser error support in 'nft
--version' output. Not worth bumping library version just for that, so
drop it again.

Fixes: b315dd551dd96 ("parser_bison: Fix for bison < 3.6")
