Rusty Russell 1764d6c907 grind_htlc_tx_fee: benchmark. ...

Takes 15 seconds on my laptop to do the worst-case grind:

	$ onchaind/test/run-grind_feerate 250001
	250001 iterations in 15893 msec = 63574 nsec each

It's not worth optimizing as it's 75% in libsecp:

    29.65%  run-grind_feera  run-grind_feerate  [.] secp256k1_fe_mul_inner
    23.51%  run-grind_feera  run-grind_feerate  [.] secp256k1_fe_sqr_inner
    11.04%  run-grind_feera  run-grind_feerate  [.] secp256k1_gej_double_var.part.6.constprop.34
     9.56%  run-grind_feera  run-grind_feerate  [.] secp256k1_scalar_reduce_512
     5.70%  run-grind_feera  run-grind_feerate  [.] Round

Even forcing a compile with -O3 -flto, it's only 13883 msec = 55534 nsec each.
