[PATCH] release/checks/integration: adjust timeout when no KVM

[PATCH] release/checks/integration: adjust timeout when no KVM

[Alyssa Ross]

We never use KVM for these on aarch64, but KVM may also not be used on
x86_64 if it's unavailable.  Checking for write access to /dev/kvm
should be a decent proxy for that.

Demi, hopefully this can make development on Qubes OS a bit less 
annoying (albiet still slow).
