Let tracefile has_memory and has_all_memory.

At present, tfile target thinks it has memory but ctf doesn't.
This is an oversight when I added ctf target support.  This patch
moves the implementations of to_has_all_memory and to_has_memory to
upper layer.  After this change, both tfile and ctf target think
they have memory.
