Cygwin: thread: Reset _my_tls.tid if it's pthread_null in init_mainthread().
Currently, _my_tls.tid is set to pthread_null if pthread::self()
is called before pthread::init_mainthread(). As a result, pthread::
init_mainthread() does not set _my_tls.tid appropriately. Due to
this, pthread_join() fails in LDAP environment if the program is
the first program which loads cygwin1.dll.
https://cygwin.com/pipermail/cygwin/2023-June/253792.html
With this patch, _my_tls.tid is re-initialized in pthread::
init_mainthread() if it is pthread_null.
