[PATCH] Fix build with Poppler 22.09.0

With Poppler 22.09.0, LO fails to build with:
```
/var/tmp/portage/app-office/libreoffice-7.3.5.2/work/libreoffice-7.3.5.2/sdext/source/pdfimport/xpdfwrapper/pdfioutdev_gpl.cxx:682:36: error: too many arguments to function call, expected single argument 'start', have 3 arguments
    state->getLineDash(&dashArray, &arrayLen, &startOffset);
    ~~~~~~~~~~~~~~~~~~             ^~~~~~~~~~~~~~~~~~~~~~~
/usr/include/poppler/GfxState.h:1506:32: note: 'getLineDash' declared here
    const std::vector<double> &getLineDash(double *start)
                               ^
1 error generated.
```

Poppler changed the getLineDash interface:
```
-    void getLineDash(double **dash, int *length, double *start)
+    const std::vector<double> &getLineDash(double *start)
```
