[PATCH 3/4] KVM: selftests: Play nice with EACCES errors in open_path_or_exit()

[Sean Christopherson <seanjc@google.com>]

Expand the SKIP conditions of the open_path_or_exit() helper to skip on
EACCES as well as ENOENT.  Most often, lack of permissions to a file
needed by a KVM selftests is due to a file being root-only by default,
not because of any bug/misconfiguration that warrants failing a test.
