Reduce image size by adding "yum clean all"

[sujaypillai]

Noticed that just adding "yum clean all" to existing "yum -y update"

alfresco-docker-base-java/Dockerfile

Line 13 in f3de686

RUN yum -y update \

RUN yum -y update
nss-3.36.0-5.el7_5
bind-license-9.9.4-61.el7 \
curl-7.29.0-46.el7
systemd-219-57.el7
glibc-2.17-222.el7
openssl-libs-1.0.2k-12.el7
krb5-libs-1.15.1-19.el7
libgcc-4.8.5-28.el7_5.1
libstdc++-4.8.5-28.el7_5.1
procps-ng-3.3.10-17.el7_5.2 && yum clean all

helps in reducing image size from 512Mb to 461Mb for JRE 10.
