[mount] Drop noatime for baseline and btrfs defaults

The usage of noatime has subtle negative impacts on the system,
including breaking various utilities that rely on that information.

If a user or distribution explicitly chooses this, then they
acknowledge this problem and account for it, but it should not be
an uninformed default.

It's left in place for swap because it does not matter there and
likely reduces thrashing for swap files.
