MINOR: stktable: add stksess_getkey() helper

stksess_getkey(t, ts) returns a stktable_key struct pointer filled with
data from input <ts> entry in <t> table. Returned pointer uses the
static_table_key variable. Indeed, stktable_key struct is more convenient
to manipulate than having to deal with the key extraction from stktsess
struct directly.
