Don't rely on specific order of shade relocations.

Fixes https://bukkit.atlassian.net/browse/BUKKIT-5458

Some maven versions would do the shade relocations in different orders, causing libraries that were relocated into org.bukkit.craftbukkit to get relocated again into org.bukkit.craftbukkit.v${minecraft_version}. Sometimes files follow that relocation rule twice and end up in org.bukkit.craftbukkit.v${minecraft_version}.v${minecraft_version}.

With this fix, my compiled jars have the same files in the same locations as the released jar at dl.bukkit.org.
