Subject: [PATCH] suppress error output from pkg-config

under normal circumstances, any errors will be noticed already by the
pkg-config --exists call, which is silent anyway. therefore this doesn't
change anything in normal qmake usage.

however, lupdate's and creator's evaluators skip the --exists calls and
subsequently invoke the normal query, which then prints useless noise to
the terminal.

Task-number: QTBUG-28159
