Joshua Peraza 78bcb55e1c Construct ProcessMemoryLinux using PtraceConnection
Update ProcessMemoryLinux to be constructed from PtraceConnection
instead of being Initialize()d with a pid_t.

This allows consolidating PtraceClient's BrokeredMemory with
ProcessMemoryLinux and providing the PtraceConnection as a alternative
to the memory file (previously only done for brokered connections).
