<h3>Log Message</h3>
<pre>REGRESSION (<a href="http://trac.webkit.org/projects/webkit/changeset/194660">r194660</a>): Legacy WebProcess crashes in ChildProcess::initializeSandbox()
https://bugs.webkit.org/show_bug.cgi?id=153734
<rdar://problem/24433179>
Reviewed by Dan Bernstein.
Fixes an issue where clients that used the legacy WebProcess bootstrapping process would crash.
Additionally, only consider the extra initialization parameter user-directory-suffix for
unsigned apps (e.g. WebKitTestRunner).
