Tests: updated ssl_engine_keys.t test.
After merge with libp11, pkcs11 engine shared object was renamed
from "engine_pkcs11.so" to "pkcs11.so". Changed configuration
accordingly.
Additionally, changed "init" to "1" in the engine configuration. This
keeps pkcs11 engine loaded and prevents segmentation faults observed
during nginx shutdown.
While here, restored correct order of ssl_certificate and ssl_certificate_key.
