Brian Goff de0f898e39 Automatically set may_detach_mounts=1 on startup ...

This is kernel config available in RHEL7.4 based kernels that enables
mountpoint removal where the mountpoint exists in other namespaces.
In particular this is important for making this pattern work:

```
umount -l /some/path
rm -r /some/path
```

Where `/some/path` exists in another mount namespace.
Setting this value will prevent `device or resource busy` errors when
attempting to the removal of `/some/path` in the example.

This setting is the default, and non-configurable, on upstream kernels
since 3.15.
