    [gdb/testsuite] Fix timeout in gdb.threads/vfork-multi-inferior.exp

    With test-case gdb.threads/vfork-multi-inferior.exp I get either:
    ...
    (gdb) run &
    Starting program: vfork-multi-inferior-sleep
    (gdb) PASS: $exp: method=non-stop: run inferior 2
    [Thread debugging using libthread_db enabled]
    Using host libthread_db library "/lib64/libthread_db.so.1".
    inferior 1
    [Switching to inferior 1 [<null>] (<noexec>)]
    (gdb) PASS: $exp: method=non-stop: inferior 1
    ...
    or:
    ...
    (gdb) run &
    Starting program: vfork-multi-inferior-sleep
    (gdb) PASS: $exp: method=non-stop: run inferior 2
    inferior 1^M
    [Switching to inferior 1 [<null>] (<noexec>)]^M
    (gdb) PASS: $exp: method=non-stop: inferior 1
    [Thread debugging using libthread_db enabled]^M
    Using host libthread_db library "/lib64/libthread_db.so.1".^M
    ...

    With a 16.3-based package on aarch64-linux, I ran into:
    ...
    (gdb) run &
    Starting program: vfork-multi-inferior-sleep
    (gdb) PASS: $exp: method=non-stop: run inferior 2
    inferior 1
    [Switching to inferior 1 [<null>] (<noexec>)]
    (gdb) [Thread debugging using libthread_db enabled]
    Using host libthread_db library "/lib64/libthread_db.so.1".
    FAIL: $exp: method=non-stop: inferior 1
    (timeout)
    ...

    Unfortunately I have not been able to reproduce this.

    Fix this using -no-prompt-anchor.

    See also commit 5f69c00a6e0 ("[gdb/testsuite] Fix timeout in
    gdb.base/async-shell.exp").
