9pfs: only test case changes this time

* Fix occasional test failures with parallel tests.
 
 * Fix coverity error in test code.
 
 * Avoid error when auto removing test directory if it disappeared
   for some reason.
 
 * Refactor: Rename functions to make top-level test functions fs_*()
   easily distinguishable from utility test functions do_*().
 
 * Refactor: Drop unnecessary function arguments in utility test
   functions.
 
 * More test cases using the 9pfs 'local' filesystem driver backend,
   namely for the following 9p requests: Tunlinkat, Tlcreate, Tsymlink
   and Tlink.
