same-inode: don't assume memory objects have ino

* lib/same-inode.h (psame_inode): Do not assume shared and/or
typed memory objects have reliable st_dev and st_ino when given to
stat-like functions, as POSIX does not guarantee this.
I don’t know of any such platforms (QNX perhaps?) but it’s
easy to be safe.
