Updated moodle package fixes security vulnerabilities

In Moodle before 2.8.7, phishing is possible when redirecting to external site using referer headers in error messages (CVE-2015-3272). In Moodle before 2.8.7, several web services returning user information did not clean text in text custom profile fields, leading to possible XSS (CVE-2015-3274). In Moodle before 2.8.7, possible Javascript injection was discovered in the SCORM module (CVE-2015-3275). As Moodle 2.6 is no longer supported, users of this package on Mageia 4 are advised to migrate to Mageia 5.
