shadow: fixed nscd to ignore exit 1 code

Note:

If nscd is installed but not in use, then running `nscd -i` will exit(1).
We shouldn't warn in this case since this is not abnormal behavior.

Example: useradd
---------------------------------------------------------------------------
useradd: nscd exited with status 1useradd: Failed to flush the nscd cache.
---------------------------------------------------------------------------
