[nft PATCH v2 2/2] src: Call bison with -Wno-yacc to silence warnings

[Phil Sutter]

Bison-3.3 significantly increased warnings for POSIX incompatibilities,
it now complains about missing support for %name-prefix, %define,
%destructor and string literals. The latter applies to parameter of
%name-prefix and all relevant %token statements.
