Subject: [PATCH] Replace absolute Qt lib dir in .prl files

In the case of building a Qt module repository against an installed
qtbase the .prl files contain absolute paths to Qt dependencies e.g.
'/install-prefix/lib/libQt5Core.so'.

Those must be replaced with $$[QT_INSTALL_PREFIX]. The .prl
replacement code however only takes $$MODULE_BASE_OUTDIR/lib into
account.

(cherry picked from commit f00de3322e05c62021082463b6de24805afc1355)

Fixes: QTBUG-75804
