add --releasever=/ to mkimage-yum.sh

I didn't realize the commit required a Docker-DCO so it failed the travis-ci build. So I removed the commit from my forked repo. Now it looks like there is a pull request with no commit. So here it is again:

Needed to add '--releasever=/' flag to run yum groupinstall on Centos7 (didn't try on anything else). This snippet from yum man page explains why:

```
Note: You may also want to use the option --releasever=/ when creating the installroot as otherwise the $releasever value is taken from the rpmdb within the installroot (and thus.  will  be  empty,  before  creation).
```

Fix Interactive container hangs when redirecting stdout
Fix #8259 - Can't reuse symlink'd bindmount

volumes.Get was not checking for symlinked paths meanwhile when adding a
new volume it was following the symlink.
So when trying to use a bind-mount that is a symlink, the volume is
added with the correct path, but when another container tries to use the
same volume it got a "Volume exists" error because volumes.Get returned
nil and as such attempted to create a new volume.
