Subject: [PATCH 2/6] Fix failure when confname is not given, use default
ep11tok.conf instead.
Slight rework on the way how the ep11 token config file is found:
If env has no OCK_EP11_TOKEN_DIR
if confname is not null, try to use it
if this fails, try ock default config dir + confname
if this fails, try ock default config dir + ep11tok.conf
if OCK_EP11_TOKEN_DIR given then
if confname is not null, try OCK_EP11_TOKEN_DIR + confname
if this fails, try OCK_EP11_TOKEN_DIR + ep11tok.conf
if still unsuccessful then token init will fail.
