The exist code of a posix compilant shell is 0..255.  Attempting to
return -1 will error in some shells and implicitly cast to 255 in
others.  Fix it by returning a legal return value.

[CI] Ensure rat ignores rust cargo lock files [CI] Ensure rat ignores emacs backup files [CI] Ensure rat ignores .egg-info (#3314)

The existing RAT ASF license auditing logic ignores any failure in the

Adjust the logic such that failure of the various tools in the
pipeline are not elided away.
