test suite: sbuild-gitish: Insist on using "build" chroot

In "test suite: sbuild-gitish: Find sbuild rune in the manpage" aka
f5c0d33ede8a we accidentally switched from "build" to "jessie".
Randomly messing about with the user's "jessie" chroot is not very
nice.  (And it would break in a hypothetical formal test providing the
x-dgit-schroot-build capability.)
