Eoghan Glynn 285c75e7a4 Allow mongod service to launch on Fedora
Fixes bug 1144907

Previously, the mongod service may fail to launch, if the eager
filesystem freespace check trips over an SELinux AVC or finds
a lack of freespace (depending on the up-to-datedness of the
selinux-policy-targeted package and the disk size/usage in the
hosting instance).

We work around these issues by ensuring the selinux-policy-targeted
package is up-to-date when ceilometer is enabled on Fedora, and
also setting the --smallfiles option.
