In comparison to the original patch we have slightly corrected iSeries
and pSeries detection according to Alexander Graf's comments on
util-linux@vger.kernel.org. Maybe we would need to add some more code
to detect pSeries emulated by Qemu/KVM.

rename: allow renaming in subdirectories

Earlier the rename(1) considered path as possible string to be renamed,
could lead to an issue with none existing destination.  See below for
demonstration of this issue.  After this change all directory elements
are ignored when the match finding happens.

$ cd $(mktemp -d)
$ mkdir aa ab
$ touch a{a,b}/aa
$ rename -v a x */aa
rename: aa/aa: rename to xa/aa failed: No such file or directory

tests: add rename(1) checks

Check basic file moves, symlink relinking, and both file moves and
symlinks when operations are have directory in destination path.
