build: qt-utils: Revert setting QT_PLUGIN_PATH exactly.

Fixes <https://issues.guix.gnu.org/57742>.

The documentation of Qt states that it is a supported use case to mix Qt 5 and
Qt 6 plugins in QT_PLUGIN_PATH [0].  This reverts the change to QT_PLUGIN_PATH
introduced in 1f466ed6be9 ("build: qt: Add qtbase argument and wrap Qt
environment variables exactly.").
