fileset: rewrite andset() to not use mctx.narrow()
New code is less efficient than the original, but it helps porting andset()
to matcher composition. This will be cleaned up later.
This effectively disables the fullmatchctx magic since mctx will never be
demoted to the matchctx. The fullmatchctx class will be removed later.
