[packaging] Add 64bit compile fix

This fixes https://build.jollamobile.com/package/live_build_log?arch=x86_64&package=pulseaudio-policy-enforcement&project=nemo%3Amw%3Anext&repository=latest_x86_64

Will upstream later on.

My first [PATCH x/y] commit, got confused by such renumbering/rehashing: https://github.com/sledges/pulseaudio/commit/0c7a67353e60409809e91d042da0614fb82b3d67
so created new numbering - 0101-...patch, hope all ok
