Mike Hommey 696cb0cc9c Bug 1625696 - Update winchecksec and build/use it natively for Linux. r=dmajor
Now that upstream winchecksec builds and works natively on Linux, use
that. That should solve the random crashes under Wine. If random crashes
still happen, it will be easier to debug anyways.
We bump to the last version that doesn't use vcpkg because vcpkg makes
things more difficult.
