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
shell pipeline rather than just the exit code of the final grep.
Adjust the logic such that failure of the various tools in the
pipeline are not elided away.
