Subject: RepoConfigLoader: masters eclass override order

Only append the current repo to eclass_locations if it's not there
already. This allows masters to have more control over eclass override
order, which may be useful for scenarios in which there is a plan to
migrate eclasses to a master repo. Thanks to Brian Harring
<ferringb@gentoo.org) for suggesting this behavior.
