parser_bison: reject non-serializeable typeof expressions

parser_bison: reject non-serializeable typeof expressions

Included bogon asserts with:
BUG: unhandled key type 13
nft: src/intervals.c:73: setelem_expr_to_range: Assertion `0' failed.

This should be rejected at parser stage, but the check for udata
support was only done on the first item in a concatenation.

After fix, parser rejects this with:
Error: primary expression type 'symbol' lacks typeof serialization

Fixes: 6e48df5329ea ("src: add "typeof" build/parse/print support")
