fix(xcatdsklspost): the diskful cleanup deleted a diskless node's postscripts

site.cleanupdiskfullxcatpost names the node type it applies to, and site.5.rst
says "on the diskfull nodes". xcatdsklspost serves every type: updatenode calls
it for a diskless or statelite node as well, and the site value is one row that
reaches all of them. With cleanupdiskfullxcatpost=yes and cleanupxcatpost=no,
append_xcatpost_cleanup still appended the delete for those nodes.

The diskful branch now reads NODESETSTATE from the generated mypostscript and
appends nothing for netboot or statelite. That is the signal remoteshell,
hardeths, configeth, otherpkgs and servicenode already use for this question,
and mypostscript.tmpl exports it.

cleanupxcatpost is unchanged. It names no node type and keeps applying to every
one, which xcatdsklspost_xcatpost_cleanup.bats now asserts so a guard added to
the wrong branch shows up.

Four cases cover it: a netboot node and a statelite node keep their postscripts,
a diskful node is still cleaned, and cleanupxcatpost still empties a netboot
node. The first two fail against the parent commit.
