Potential PEAR installation related code block found

[rodrigoprimo]

I found a code block that I believe is related to the now unsupported PEAR installation (#4) that can be removed:

PHP_CodeSniffer/src/Config.php

Lines 1707 to 1711 in 038b4a1

	if (is_file($configFile) === false
	&& strpos('@data_dir@', '@data_dir') === false
	) {
	$configFile = '@data_dir@/PHP_CodeSniffer/CodeSniffer.conf';
	}

A similar code block was removed in #4:

Opening this issue first for confirmation before creating a PR.

Good find. I do believe you are correct and that this is related to PEAR installs, though might be good to confirm via a git blame ?

Looking at that second condition makes my brain hurt no matter what....

Once confirmed, happy to merge a PR to remove this. If we want to play it safe (if there are any doubts), the PR should be pulled to 4.x. Otherwise it can go into 3.x.
