linux-user: Use public sigev_notify_thread_id member if available
_sigev_un._tid is an internal glibc field and is not available on
musl libc. The sigevent(7) man page and Linux UAPI headers both use
sigev_notify_thread_id as a public way to access this field.
musl libc supports this field since 1.2.2[0], and glibc plans to
add support as well[1][2].
If sigev_notify_thread_id is not available, fall back to _sigev_un._tid
as before.
