ptrace/um: Replace PT_DTRACE with TIF_SINGLESTEP
commit c200e4bb44e80b343c09841e7caaaca0aac5e5fa upstream.
User mode linux is the last user of the PT_DTRACE flag. Using the flag to indicate
single stepping is a little confusing and worse changing tsk->ptrace without locking
could potentionally cause problems.
So use a thread info flag with a better name instead of flag in tsk->ptrace.
Remove the definition PT_DTRACE as uml is the last user.
