tests: don't include plain 'diff -U0' content in test-diff-unified.t
The only purpose of 'diff -U0' was to show that 'hg diff -U0' did almost the same.
Unfortunately 'diff -U0' on Solaris gives incorrect line numbers. Masking it
with globs wouldn't it make sense, so removing it is the best solution.
