    PR server/18081: gdbserver crashes when providing an unexisting binary

     $ ./gdbserver :1234 blah
     Process blah created; pid = 16471
     Cannot exec blah: No such file or directory.

     Child exited with status 127
     Killing process(es): 16471
     ../../../../src/binutils-gdb/gdb/gdbserver/linux-low.c:920: A problem
internal to GDBserver has been detected.
     kill_wait_lwp: Assertion `res > 0' failed.

    GDBserver shouldn't even be trying to kill that process.  GDBserver
    kills or detaches from all processes on exit, and due to a missing
    mourn_inferior call, GDBserver tries to kill the process that it had
    already seen exit.

    Tested on x86_64 Fedora 20.  New test included.  I emulated what
    Windows outputs by hacking an error call in linux_create_inferior.
