delete the Dockerfile-55 file and rename Dockerfile-56 to Dockerfile-5

Since 5.5 and 5.6 dockerfiles are identical execept the base image php version.
Will let the users switch the php 5.6 and 5.5 version from the Dockerfile-5 by changing one char
in the first line. Removing this duplication will make contribution and maintance easier and faster.
