gokrazy: add two arm64 variants for Pi & VMs

Browse Source 
We previously had two GOARCH variants for natlab testing
(gokrazy/natlabapp and gokrazy/natlabapp.arm64), but we didn't have
those variants for the "tsapp" (production, not testing) variant.

This adds arm64 for tsapp too. But there are two major users of arm64
for gokrazy: Raspberry Pis, and cloud VMs. So make two variants.

Updates #1866
