update github.com/cyphar/filepath-securejoin to v0.5.1

Browse Source 
Since this will be required by the runc security update I bump it hare
already to make the runc bump easier. Note while there is 0.6.0 out we
use 0.5.1 intentionally as 0.6 comes with breaking changes that won't
build in our dependencies.

Also note the lib now contains code licensed under MPL-2 which is not
yet approved by the CNCF[1] but because the runc fix requires it we were
advised to just go ahead and update it for now.
