crypto/internal/fips140/rsa: do trial divisions in key generation
This is optimized to be cheap in terms of extra code and complexity,
rather than performance, so we reuse the GCD we have for inverting d.
Recovers most of the performance loss since CL 630516, although
benchmarking key generation is by nature extremely noisy.
