Fix exit code for check_line_terminators.sh (#7970)

Browse source 
If there are *no* files with CRLF line endings, then the xargs exits with a
non-zero exit code (as expected), but then, since that is the last thing to
happen in the script, the script as a whole exits non-zero, making the whole
thing fail.

using `if/then/fi` instead of `&& (...)` means that the script exits with a
zero exit code.
