There are rpm versions that require access to /dev and fail
with the error message 'Failed to initialize NSS library'
For details see: https://bugs.centos.org/view.php?id=14767
Due to the rpm location checkup fix from Issue #1037 this
change impacts builds for distributions that uses an rpm
version with the above behavior (e.g CentOS) and fails as
consequence of the rpm call error. This commit fixes this
in a way that we make sure the host /dev is available at
the time of the call.
