    tests: Remove some redundant writes
    
    `ret` was never read. This fixes scan-build warnings:
    ```
    ../../../../source/glib/glib/tests/thread.c:148:8: warning: Although the value stored to 'ret' is used in 
the enclosing expression, the value is never actually read from 'ret' [deadcode.DeadStores]
      if ((ret = prlimit (getpid (), RLIMIT_NPROC, &nl, &ol)) != 0)
           ^     ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    ../../../../source/glib/glib/tests/thread.c:174:8: warning: Although the value stored to 'ret' is used in 
the enclosing expression, the value is never actually read from 'ret' [deadcode.DeadStores]
      if ((ret = prlimit (getpid (), RLIMIT_NPROC, &ol, NULL)) != 0)
           ^     ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    ```
