linux-procfs: Handle lowercase "t (tracing stop)" state
Since Linux 2.6.33, /proc/PID/status shows "t (tracing stop)", with
lowercase 't'. Because GDB is only expecting "T (tracing stop)", GDB
can incorrectly suppress errors in check_ptrace_stopped_lwp_gone:
1578 if (!check_ptrace_stopped_lwp_gone (lp))
1579 throw_exception (ex);

* nat/linux-procfs.c (parse_proc_status_state): Handle lowercase
