Allow copy-builtin to work with modified sources

Browse Source 
`scripts/make_gitrev.sh` had 'set -e' so if any command failed it would
fail and cause copy-builtin to fail (copy-builtin also has `set -e`.
This commit also simplifies scripts/make_gitrev.sh to always write a
file by using a cleanup function.  It also simplifies other areas of
the script as well (making it much shorter).
