sigrok-cross-mingw: patch for boost numeric literals issue in MXE builds

Patch the pulseview cmake instructions within sigrok-util until the
pulseview.git repository builds out of the box. General applicability
of the compiler switch on all platforms is yet to get determined.

+Newer boost versions phrase numeric literals in ways that are not
+supported out of the box. Pass a compiler switch which unbreaks the
+Pulseview build with current MXE (as of 2022-02). See bug 1771.
+
+TODO It is yet to get determined whether the CMakeLists.txt change is
+universally applicable to all supported platforms and compiler versions
+that are used with Pulseview (after all non-default compiler behaviour
+is enabled). When the pulseview.git repository contains the change,
+then this patch becomes obsolete.
