But on Linux (and not on the BSD systems), this has the effect that
vma_iterate() produces a truncated list of VMAs. This fixes it.

        vma-iter: Fix truncated result on Linux (regression from 2017-09-26).
        * lib/vma-iter.c (MIN_LEFTOVER): New macro.
        (STACK_ALLOCATED_BUFFER_SIZE): Set to a minimal value if not needed.
        (rof_open): On Linux, do multiple read() calls and make sure
        MIN_LEFTOVER bytes are left when read() returns.
