Doug Davis 5d2fe159f4 Docker run -e FOO should erase FOO if FOO isn't set in client env ...

See #10141 for more info, but the main point of this is to make sure
that if you do "docker run -e FOO ..." that FOO from the current env
is passed into the container.  This means that if there's a value, its
set.  But it also means that if FOO isn't set then it should be unset in
the container too - even if it has to remove it from the env.  So,
   unset HOSTNAME
   docker run -e HOSTNAME busybox env
should _NOT_ show HOSTNAME in the list at all

Closes #10141
