The core of a star won't be travelling at or even near the speed of light.

Light only travels at 'the speed of light' because a particle of light, or a photon, is massless and can reach such speeds because of it's zero mass.

A core of a star has MASSIVE mass, and so could only ever travel at best, at a fraction of the speed of light.

So, a star going supernova 60K years ago, assuming it is 60K light years distant, means we would see the explosion as though it's happening now, in real the light photons spewing from the explosion would take 60K years to reach our eyes and instruments (as it takes 1 Solar year for light to travel 1 light year)...remant debris, including parts of a super dense core, would take perhaps hundreds of thousands, probably millions of years to reach Earth, depending on how fast the debris is moving...but it's certainly nowhere near the speed of light.

To answer the mind experiment though...yes, if ALL of Earth's resources and people, worked on building craft and setting up off world bases etc, and did NOTHING else, no normal manufacture, no consumerism, no pure research but worked constantly and exclusively on an evacuation project...i think we could get a significant percentage, if not all of Earth's population to either Mars or one of the Jovian or Saturnian moons within 75 years...or less.
