Andreas Kling 643f2884cc LibCore: Fix signal handler deadlock in EventLoopImplementationUnix 
handle_signal() called ThreadData::the() which can acquire a write
lock on s_thread_data_lock if the thread hasn't initialized its
ThreadData yet. If the signal interrupts a thread that already holds
a read lock on s_thread_data_lock (e.g. in unregister_notifier()),
this deadlocks — the write lock waits for the read lock, but the
read lock holder is blocked in the signal handler.

Fix by accessing the thread-local s_this_thread_data directly. If
the thread has no ThreadData, there's no wake pipe to write to, so
we just return.
