Fixed shell start script failure on missing memory settings in conf file

Before that fix, the startYACY.sh failed when the javastart_Xmx or
javastart_Xms configuration keys were missing for some reason from
yacy.conf file, with the error "Unrecognized option: - Error: Could not
create the Java Virtual Machine."
