datatype: add DTYPE_F_CLONE flag
This flag allows us to identify datatypes that are instances from
original datatypes.
This fixes a possible double free when attaching a concatenation
datatype to set->keytype while being also referenced from concatenation
expressions.
ip6/flowtable.t: ERROR: line 5: src/nft add rule --debug=netlink ip6 test-ip6 input flow table acct_out { meta iif . ip6 saddr timeout 600s counter }: This rule should not have failed.
*** Error in `src/nft': double free or corruption (fasttop): 0x000000000117ce70 ***
