[RELEASE] fix docker mount volume issue

Descriptions of the changes in this PR:

* Motivation

 apache#1674 introduced a regression for running release scripts on mac.
 the destination should be "/home/${USER}" rather than ${LOCAL_HOME}.
 because the docker os is linux. Otherwise the gpg keys can not propagated
 correctly from host machine to docker.

* Changes

 Use `/home/${USER}` as the destination path
