Ensure idempotency between Puppet runs

Running RHEL 7.1 with 'yum' provider, puppetlabs-rabbitmq is not
idempotent.
After a second run, puppet tries to change the SElinux context:
/File[/etc/systemd/system/rabbitmq-server.service.d]/seltype: seltype
changed 'rabbitmq_unit_file_t' to 'systemd_unit_file_t'

Since packaging already manages SElinux labels, we should not let Puppet
doing it (default behavior).
This patch aims to set selinux_ignore_defaults to True for the File
resource (/etc/systemd/system/rabbitmq-server.service.d).

Thanks to that patch, Puppet will be indempotent between all runs on
RHEL platforms.
