*.service files should be world-readable

[chriskuehl]

Currently the service files are installed with 640 permissions:

ckuehl@whirlwind:~$ ls -l /lib/systemd/system/mesos*.service
-rw-r----- 1 root root 215 Jul 27 13:45 /lib/systemd/system/mesos-master.service
-rw-r----- 1 root root 271 Jul 27 13:45 /lib/systemd/system/mesos-slave.service

These should be 644 or similar. As is, this produces warnings all the time:

Aug 03 13:39:02 whirlwind systemd[1]: Configuration file /lib/systemd/system/mesos-slave.service is marked world-inaccessible. This has no effect as configuration data is accessible via APIs without restrictions. Proceeding anyway.

These go both to syslog and to the console when running certain systemd commands.

The warnings are correct of course (try systemctl show mesos-slave as non-root).
