tests: force `seq` to print with '\n' EOL
It looks like consistent EOL is the reason for 0605726179a0, but now on py3,
`print()` uses the platform EOL without regard to binary mode. The tests mostly
use this to loop over a sequence of number in the shell, but there are a handful
that redirect output to a file. Specifically, this fixes Windows runs of
`test-bundle2-multiple-changegroups.t`, but there may be other tests this fixes.
Some other `tests/*.py` files also set binary mode on stdout, but they also
write bytes directly to `sys.stdout.buffer`. I'm not doing that here because
PyCharm flags these write calls for passing bytes instead of str (PyCharm is
likely wrong, but possibly confused because the code falls back to `sys.stdout`
if there is no `.buffer` attribute), and it's annoying.
