Fix tc03_check_API_passwd_allow

[Issue#]       SSDWSSP-559
[Bug/Feature]  tc03_check_API_passwd_allow was failing randomly.
[Cause]        SS needed to be restarted after clearing
               opt/data/security-server/ folder.
[Solution]     Fix bugs and adapt the test case to the new security
               server in both smack and non-smack test versions.
               Additionally, reset_security_server() has beed moved to
               security_server_clean_env.cpp.
[Verification] Build, install and run the test case.
