Merge FreeBSD changes from usr.bin/cpio to contrib/libarchive/cpio:

r204111 (uqs):
Fix common misspelling of hierarchy

r211054 (kientzle);
Fix -R when used with -p.  Previously, the
uname and gname weren't overwritten, so the
disk restore would use those to lookup the
original uid/gid again.  Clearing the uname
and gname prevents this.

r212263 (gjb):
Fix typo in bsdcpio manual:
s/libarchive_formats/libarchive-formats

MFC after:	2 weeks
