Prefer QT_PLUGIN_PATH over compiled-in paths.

Currently, when one compiles a Qt plugin that is also installed
system wide to a local path added to QT_PLUGIN_PATH, you have no
way to ever load it as the global plugin will always be preferred.
This is due to the order in which the QCoreApplications::libraryPaths
are constructed, which always appended the QT_PLUGIN_PATH contents
to the end.

Now, the QT_PLUGIN_PATH contents are put first, such that the plugins
in there are preferred and loaded.

[ChangeLog][QtCore][QPluginLoader] Fixed the search order of Qt plugins
so that paths specified by the QT_PLUGIN_PATH environment variable
are searched before built-in paths.
