QDoc: Remove dead code in ClangCodeParser

ClangCodeParser::buildPCH included a local variable, privateHeaderDir,
which was written to in a loop over the parser's includeDaths private
member, but never read. This patch removes the local variable and loop
from said method, as it is effectively dead code.
