[Toybox] [PATCH] ps: Allocate stdout buffer on heap.

[Peter Collingbourne]

The top command exits via a call to xexit() from toy_exec_which(). At
this point we call exit handlers including top_cursor_cleanup(),
which will write to stdout, resulting in an attempt to use the stdout
buffer which was allocated in top_common()'s stack frame, which no
longer exists. Fix it by having top_common() allocate the stdout
buffer on the heap.
