Short answer, you can't.

Long answer, --installroot is particularly useful if you want to
create/work on an alternate root installation, e.g. when rescuing a
broken system, or installing an OS template for a VPS. If you want to
move the binary location of some (not all) packages (e.g. move bash
from /bin/bash to /opt/bash/bin/bash), then you can't do that with yum
and normal distro-provided rpm. You need to create a special rpm for
that. See http://www.rpm.org/max-rpm/s1-rpm-reloc-building-relocatable.html
