[PATCH tools/memory-model 2/4] tools/memory-model: Remove mention of docker/gentoo image

["Paul E. McKenney" <paulmck@linux.vnet.ibm.com>]

Because the docker and gentoo images haven't been updated in quite some
time, they are likely to provide more confusion than help.  This commit
therefore removes mention of them from the README file.
