QQmlJSUtils: Accept a relative path in qmlSourcePathFromBuildPath()

qmlSourcePathFromBuildPath() found the module through a clean absolute
form of the path, then cut the module's absolute directory off the path
as passed in. qmllint passes the linted file's path as given on its
command line, so linting a build-folder copy by a relative path with
--resource read past the end of the string and crashed, for example:

    cd build && qmllint --resource .qt/rcc/qmake_Mod.qrc \
        --resource .qt/rcc/Mod_raw_qml_0.qrc Mod/Main.qml

Cut the module directory off the clean absolute path instead.
