test: tmpd: Replace createVpnorRoot() with VpnorRoot class
The VpnorRoot class prepares a temporary directory for use as a VPNOR backing store. Implementing it as a class allows us to use RAII to get it to clean up after itself. Change-Id: Ia5a839e751f8dc2126a4c0b474e9a7b8593cfd57 Signed-off-by: Andrew Jeffery <andrew@aj.id.au>
