ossfuzz: Fix expr target build failure

Google oss-fuzz reported a build failure for the OVN expression parser.
Upon investigation, it turned out that the expr_parse_target fuzzer was
 not being run by Google due to the said failure.

The root cause of the build failure turned out to be a change in the
definition of the expr_parse_string() API. Now, this API accepts an
additional parameter of type struct sset * that points to the set of
 address set referenced which may be NULL if unused.

This patch adds this additional parameter to expr_parse_string()
setting the pointer to the set of address set referenced to NULL.

Once this patch is applied, ossfuzz's expr_parse_target should build
 and subsequently be fuzzed.
