[bug#33390] [PATCH 1/4] qtwebkit: Fix pri install directory.

[ericbavier@centurylink.net]

From: Eric Bavier <bavier@member.fsf.org>

This lets qmake find qtwebkit components, allowing packages like python-pyqt
to find qtwebkit and enable support.

* gnu/packages/qt.scm (qtwebkit)[arguments]: Add "ECM_MKSPECS_INSTALL_DIR"
to #:configure-flags.  Link with "--no-keep-memory".
