expression: constant range is not a singleton

Remove the EXPR_F_SINGLETON flag in EXPR_RANGE_VALUE so it can be used
in maps.

expr_evaluate_set() does not toggle NFT_SET_INTERVAL for anonymous sets
because a singleton is assumed to be place, leading to this BUG:

 BUG: invalid data expression type range_value
 nft: src/netlink.c:577: netlink_gen_key: Assertion `0' failed.
