Hurd: Adjust to changes to "push pruning old threads down to the target"
For "info threads", we currently run into:
$ gdb/gdb -q -nw -nx --batch -ex start -ex info\ threads bfd/doc/chew
Temporary breakpoint 1 at 0x80486e0: file ../../../W._C._Handy/bfd/doc/chew.c, line 1535.
[New Thread 10656.5]
Thread 4 hit Temporary breakpoint 1, main (ac=1, av=0x102cd84) at ../../../W._C._Handy/bfd/doc/chew.c:1535

Id Target Id Frame

Before commit e8032dde10b743253125d7defb5f5503b21c1d26,
gdb/thread.c:update_thread_list used to call prune_threads, after that change
it doesn't anymore, and we don't implement the to_update_thread_list target
method where the prune_threads call got moved. For now, apply a fix, related
to commit c82f56d9d760a9b4034eeaac44f2f0fa5779ff69 "Hurd: Adjust to
startup-with-shell changes", which restores the previous behavior:

Not perfect, but at least better.

* gnu-nat.c (gnu_create_inferior): After startup_inferior, call
prune_threads.
