crypto/internal/fips140: update frozen module version to "v1.0.0"

We are re-sealing the .zip file anyway for another reason, might as well
take the opportunity to fix the "v1.0" mistake.

Note that the actual returned version change will happen when re-sealing
the .zip, as the latest mkzip.go will inject "v1.0.0" instead of "v1.0".

This reapplies CL 701518, reverted in CL 702255.
