ocf_mkstatedir: fix path check

Check fails due to duble slashes in string comparison.

Path /var/run/apache2 is compared with /var/run//* giving the following error in the logs:

Dec 21 13:17:53 node1 apache(apache_/etc/apache2/apache2.conf)[826]: [868]: ERROR: cannot create /var/run/apache2 (does not start with /var/run/)
