test/gen_testdata: Make sure that "with zext" and "without zext" databases differ only in transaction extension

Previously diff in between 1.zdump.zpickledis.ok and 1_!zext.zdump.zpickledis.ok
indicated difference in many data records as demonstrated in the appendix.
That was due to that !zext variant, while skipping generating
transaction extension, contrary to zext variant, did not consumed PRNG
output, and so when going further PRNG state for zext and !zext variants
was diverging.

-> Fix it via consuming PRNG output in !zext case exactly the same way
as in zext case, but throwing out ext4subj output.

After the patch the diff in between `1.zdump.zpickledis.ok
1_\!zext.zdump.zpickledis.ok` shows only differences in between
txn.extension fields:
