Remove trailing spaces from expected.txt files (excluding WPT for now since that contains too many)
https://bugs.webkit.org/show_bug.cgi?id=217016

Reviewed by Zalan Bujtas.

Done with this command:

    find LayoutTests -name '*-expected.txt' | grep -v imported | xargs awk '/^CONSOLE MESSAGE:/ { next }; /^<\?xml/ { nextfile }; { print FILENAME; nextfile }' | xargs perl -i -pe 's/ +$//g'

This affects many files, and it's not helpful to clog the change log with a list of them.
