Fix exit code for check_line_terminators.sh (#7970)
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.

# This script checks that line terminators in all repository files (excluding
# those in the .git directory) feature unix line terminators.
#
# Usage:
#
# ./check_line_terminators.sh
#
# The script will emit exit code 1 if any files that do not use unix line
# terminators are found, 0 otherwise.
# cd to the root of the repository
cd `dirname $0`/..
# Find and print files with non-unix line terminators
