Return NOT_FOUND from the set_cmnd_path() stub since we don't set user_cmnd.

Browse Source 
The purpose of set_cmnd_path() is to reset user_cmnd based on a new
runchroot.  For the stub version we don't modify user_cmnd and so
must not return a status of FOUND.
Fixes oss-fuzz issue #31250 which only affected the fuzzer and not sudo.
