Fixes the fact daily.sh does not run outside of the install directory

/bin/sh /opt/librenms/daily.sh
#!/bin/bash
Could not open input file: daily.php
#!/bin/bash
Could not open input file: daily.php
Could not open input file: daily.php
#!/bin/bash
Could not open input file: daily.php

The script now changes into the directory that daily.sh is in to run.
