In nTar(), don't return the error value when the goroutine that's populating the error value can continue running long after nTar() returns. Instead, wrap the Close() method of the pipe that we're returning in a function that collects those errors, along with any error we get from closing the pipe, and returns them from Close() wrapper.
In Build(), if the Close() method returns an error, at least log it.

Should help with #9379.

Thank you @nalind! You may need to force-push to rerun CI; looks like Cirrus can't pick up my title change.

@edsantiago no problem, looks like I needed to rebase anyway.

Rebased.

Downgrade github.com/coreos/go-systemd/v22 to a version that will build
against systemd headers that we have on CentOS 8.  This also pulls in
github.com/varlink/go.
