fgraph: Separate size of ret_stack from PAGE_SIZE
The ret_stack (shadow stack used by function graph infrastructure) is
currently defined as PAGE_SIZE. But some architectures which have 64K
PAGE_SIZE, this is way overkill. Also there's an effort to allow the
PAGE_SIZE to be defined at boot up.
Hard code it for now to 4096. In the future, this size may change and even
be dependent on specific architectures.
