Always install binaries and other files under /usr, not /.  This will
break any distribution that hasn't yet merged the two, which are
vanishingly small these days.  This breaks the usecase of needing to
repair the /usr partition when there is no initramfs or livecd
available and / is the only option.

V1 -> V2: remove root_sbindir, root_libdir, PKG_ROOT_SBIN_DIR,
          PKG_ROOT_LIB_DIR

V2 -> V3: fix debian-specific installation logic, i.e. do not
          delete /usr/lib in xfslibs-dev

Sorry I missed that on the first run... the new xfslibs-dev/xfsprogs
package paths are comparable to what got built before this patch.
