Re: [Libguestfs] [PATCH nbdkit 2/7] tests/test-debug-flags.sh: Log the error from nbdkit unconditionally.

Useful to print the error displayed by nbdkit in all cases, not
just when the test fails.

Also fix the error message if the test does fail (unexpected -> expected).

Bike-shedding: my first read was more along the lines of "I've output the file, and found the expected error message that contains $1" when the point was that the expected error message was not present.

Maybe it reads better as one of:
"expected an error message that contains: $1"
"unexpected error message, expecting: $1"

But the sense change makes sense, as does the unconditional output of the file.
