The accumulo-env.sh attempts to add Hadoop libraries to the classpath from the path $HADOOP_HOME/share/hadoop/client. There are times when Hadoop libraries are not installed in the tarball-style path, such as when Hadoop is installed via RPMs. Add the environment variable HADOOP_CLIENT_LIB_DIR to accumulo-env with a default value of $HADOOP_HOME/share/hadoop/client. Update the construction of the CLASSPATH to add hadoop libraries using the HADOOP_CLIENT_LIB_DIR variable. Closes apache#6530

Looking at lines starting at 58, the intention is to honor the CLASSPATH environment variable set by the user and put that first.

This change does not circumnavigate that intention.
