Bugzilla Bug 112618

[s]pena jzlib-1.0.7 # echo ${D}
/var/tmp/portage/jzlib-1.0.7/image/
[s]pena jzlib-1.0.7 # dodir /opt
ACCESS DENIED  chmod:     /opt
install: cannot change permissions of `/opt': Permission denied

Because dodir is a binary, ${D} is not defined in it.
export ${D} inside the sandboxshell fixes the situation.
It also seems that sandboxshell is missing metadata.xml.
