tests-999: add a random directory to mount path

Currently, the mount path is static/hard coded and sometimes there might
be corners cases where the mount path directories are not deleted
completely, or there might be two instances of CI running at the same
time. Let's introduce an additional directory to the mount path, that's
generated randomly, so that every run is unique and doesn't interfere
with each other.
