Sergey Bugaev 2f8ecb58a5 hurd: Fix x86_64 _hurd_tls_fork 
It is illegal to call thread_get_state () on mach_thread_self (), so
this codepath cannot be used as-is to fork the calling thread's TLS.
Fortunately we can use THREAD_SELF (aka %fs:0x0) to find out the value
of our fs_base without calling into the kernel.

Fixes: f6cf701efc
"hurd: Implement TLS for x86_64"

Checked on x86_64-gnu: fork () now works!
