    [gdb/testsuite] Fix gdb.threads/killed-outside.exp on aarch64
    
    On aarch64 (and likewise on arm), I run into:
    ...
    (gdb) PASS: gdb.threads/killed-outside.exp: get pid of inferior
    Executing on target: kill -9 11516    (timeout = 300)
    builtin_spawn -ignore SIGHUP kill -9 11516^M
    continue^M
    Continuing.^M
    Unable to fetch general registers: No such process.^M
    (gdb) [Thread 0xfffff7d511e0 (LWP 11518) exited]^M
    ^M
    Program terminated with signal SIGKILL, Killed.^M
    The program no longer exists.^M
    FAIL: gdb.threads/killed-outside.exp: prompt after first continue (timeout)
    ...
    due to a mismatch between the actual "No such process" line and the expected
    one:
    ...
    set no_such_process_msg "Couldn't get registers: No such process\."
    ...
    
    Fix this by updating the regexp.
    
    Tested on aarch64-linux, and x86_64-linux.
