Subject: CLEANUP: hlua: check for at least 2 threads on a task

CLEANUP: hlua: check for at least 2 threads on a task

In 1.9-dev1, commit 5bc9972ed ("BUG/MINOR: lua/threads: Make lua's tasks
sticky to the current thread") to detect unconfigured Lua tasks that could
run on any thread, by comparing their thread mask with MAX_THREADS_MASK.
The proper way to do it is to check for at least 2 threads in their mask
in fact. This is more reliable and allows to get rid of MAX_THREADS_MASK
there.
