Revert "add sal*Int64 conversions to BigInt"
This reverts commit 5dae4238ea6e21df42f4437a43d152954fc494fd, which appears
to
have ambiguitiy problems not only on Windows, but generally with 32-bit
builds
like <https://ci.libreoffice.org/job/gerrit_android_x86/1518/>:

/home/tdf/lode/jenkins/workspace/android_x86/tools/source/generic/bigint.cxx:501:18:
error: conversion from 'int' to 'const BigInt' is ambiguous
