tests: fix an erroneous stat failure with bind mounts
* tests/misc/stat-mount: Don't try to correlate the
mount points output by df and stat, as they're similar,
but sometimes different in the presence of bind mounts.
* doc/coretuils.texi (stat invocation): Clarify the
bind mount difference between stat and df.
