my_thread: Use unsigned long long for storing pthread IDs

This is a fix for operating systems that have pthread_t defined
as a pointer and use the default pthread_self() mechanism for
identifying threads. More specifically, this is a build fix
for NetBSD.

Any changes I submit are freely available under the new BSD
license.
