Change the transport pipe and dbgshim runtime startup semaphores permissions to user only

Since the mechanism used to enumerate process modules (/proc/xxxx/maps on Linux, running
vmvmap on OSX) is user only and the default group new users get on OSX is the same ("staff")
restricting the transport pipes and runtime startup named semaphores to user only is the
right way to go.

If we find some reason to give groups permissions, we can always change that later though
the process module enumeration would have to be figured out.
