BUG/MINOR: lua: Add missing string length for lua sticktable lookup
In hlua_stktable_lookup(), the key length is never set so all
stktable:lookup("key") calls return nil from lua.
This patch must be backported as far as 1.9.
[Cf: I slightly updated the patch to use lua_tolstring() instead of
luaL_checkstring() + strlen()]
