[xfstests-bld PATCH] gen-tarball: add 'set -e'

[Eric Biggers <ebiggers@kernel.org>]

From: Eric Biggers <ebiggers@google.com>

The latest master branch of xfstests is missing a Makefile in
tests/ceph/, which broke xfstests's 'make install'.  But gen-tarball
didn't notice this.  Fix this by adding 'set -e', and to make this work
adjust a couple other commands that are expected to fail.
