Subject: [PATCH] src: missing destroy function in statement definitions

Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
(cherry picked from commit 4ac11b890fe870d1c066783bccc235e1922dd431)

Conflicts:
-> Dropped changes to set_stmt_destroy() and map_stmt_destroy() due to
   missing commit a55ca1a24b7b2 ("src: integrate stateful expressions
   into sets and maps")

Signed-off-by: Phil Sutter <psutter@redhat.com>
