To run commands with normal user privilege, add a new config variable
NORMAL_USER and two helper functions _run_user and _require_normal_user.
The user name specified to NORMAL_USER is used to run the commands
specified to _run_user. The test cases which require NORMAL_USER shall
call _require_normal_user to ensure the NORMAL_USER is valid.

+To run test cases which require normal user privilege, prepare a user and
+specify it to the `NORMAL_USER` variable. The test cases are skipped unless a
+valid user is specified.
