BUG/BUILD: threads: unbreak build without threads

A few users reported that building without threads was accidently broken
after commit 6b96f72 ("BUG/MEDIUM: pollers: Use a global list for fd
shared between threads.") due to all_threads_mask not being defined.
It's OK to set it to zero as other code parts do when threads are
enabled but only one thread is used.

This needs to be backported to 1.8.
