fromupstream: Wrap long TEST= lines

Putting in a particularly long --test value would cause the upload hook
scripts to complain of a long line. This wraps TEST= lines to 75
characters, the length recommended by that lint error.

BUG=none
TEST=`fromupstream.py --test "$LONG_TEST_MESSAGE" ...` produces lines
     wrapped to 75 characters.
