Append -W* configure flags to QMAKE_C*FLAGS_WARN_ON

... instead of adding them to all C*FLAGS. This makes it
possible to pass -Wno-warning-name to configure to disable
certain warnings enabled by default (which didn't work
previously). This also has the added benefit that only projects
that have CONFIG+=warn_on will get the extra warning flags.
