Use private yum cache dir in build scripts

YUM & friends use a cache directory named /tmp/yum-$USER-xxx or
similar, even when used concurrently e.g. when bulding unrelated
source trees. This causes interference between CI pipelines.

This patch sets TMPDIR=$MY_WORKSPACE/tmp when calling repoquery,
etc.
