No need to waste time by forcing creation of more than 1000 blocks to get the benefits of being able to test BIP 66. Also, reducing the height makes it more likely that (third-party) tests are conforming to BIP 66, which is enforced on mainnet for all new blocks.

ACK fafe896a0b870d85250927bd5374caf73d379468. Full functional test suite showed few second speed incrase on my laptop (although I didn't do proper benchmarking with multiple runs, just single time ./test/functional/test_runner.py on current master vs this PR).

This should only affect the speed of test/functional/feature_dersig.py and no other test
