Brian Warner 6dd58ceb2a tests: use oneshare=True on more test cases
This saves more time (as measured on my laptop):

* test_sftp: 17.7s -> 13s
* test_dirnode: 26.5s -> 20s
* test_ftp, test_configutil, test_web show negligible speedups

As before, some tests care about the number of shares, generally ones
which delete or corrupt shares and then expect to see the errors get
noticed or fixed. Those tests continue to use k=3/N=10.
