PermissionBackend#filter: Use Collections instead of Maps

Up until now, the ref filter method in PermissionBackend used Maps
instead of Collections. The only place where this is useful is a JGit
method for advertising refs. For most parts of Gerrit, we waste effort
in compiling the map but then only use #values.

This commit rewrites the interface and internals to use Collections
instead.
