aws_s3: simplify the template check (#740)

aws_s3: simplify the template check

Don't compare strings with \n character. This triggers errors like this:
fatal: [testhost]: FAILED! => {
    "msg": "The conditional check 'result.contents == \"template:\ntest template\n\"' failed. The error was: Invalid conditional detected: EOL while scanning string literal (<unknown>, line 1)"
}
