fix retval checks in init script template

[fraenki]

The status command in the init script is not working:

# service tomcat-foobar status
CATALINA_BASE /opt/foobar
CATALINA_HOME /opt/foobar
CATALINA_LOCAL
CATALINA_OPTS 
JAVA_OPTS 
TOMCAT_USER tomcat
/etc/init.d/tomcat-foobar: 169: [: 0: unexpected operator
pidfile exists but tomcat dead

And thus the puppet run will fail, although the application was started (or is running) correctly:

Error: Could not start Service[tomcat-foobar]: Execution of 'service tomcat-foobar start' returned 1: CATALINA_BASE /opt/foobar
CATALINA_HOME /opt/foobar
CATALINA_LOCAL
CATALINA_OPTS 
JAVA_OPTS 
TOMCAT_USER tomcat

This PR fixes the small syntax issues in the init script template.
