with this log output:

439dea1b19 Use existing build information for version if not embedded with build script
Go1.12 introduced BuildInfo which embeds build information. It does
not embed build date to facilitate reproducable builds by default.
If build information is embedded from build script, use the information
provided by the Go build system.

5582d8370c ctlsock: raise timeout to 10 seconds
There was at least one user who hit the earlier 1 second timeout. Raise to 10
seconds which ought to be enough for anyone.

c9e4e4f741 Fix reverse gocryptfs.conf access on macOS
Unlike the FUSE implementation on Linux, macFUSE doesn't cache the file
attributes from the `LOOKUP` call, so it calls `GETATTR` prior to
accessing a file.

In the case of the `VirtualConfNode` (reverse config file passthrough),
this resulted in the default `GETATTR` implementation returning an empty
result, ultimately resulting in a "permission denied" error.

    14:44:14.095207 rx 3: GETATTR n2
    14:44:14.095229 tx 3:     OK, {tA=1s {M0100000 SZ=0 L=0 0:0 0 0:8954996 A 0.000000 M 0.000000 C 0.000000}}
    14:44:14.099943 rx 4: ACCESS n2 {u=501 g=20 r}
    14:44:14.099990 tx 4:     13=permission denied

By impementing `Getattr` (from `fs.NodeGetattrer`) on `VirtualConfNode`
this solves the issue.

a2b54cfccd root_test: fix leftover loop mount
After running "make root_test" a few times df would look like this,
no good:

Turns out the unmount failed with EBUSY, so use lazy
unmount.
