Subject: [PATCH] FAPI: Skip test fapi-fix-provisioning-with template if no
 certificate is available.

If the configure option --enable-self-generated-certificate is not used this
test can't be executed because no certificate will be stored in NV ram. The
test will be skipped if no certificate is available.
Fixes: #2558
