    gdbserver: use current_process in ps_getpid
    
    The following patch ("gdbserver: switch to right process in
    find_one_thread") makes it so find_one_thread calls into libthread_db
    with a current process but no current thread.  This tripped on ps_getpid
    using current_thread in order to get the process' pid.  Get the pid from
    `current_process ()` instead, which removes the need to have a current
    thread.  Eventually, it would be good to get it from the
    gdb_ps_prochandle_t structure, to avoid the need for a current process
    as well.
