PATCH: Use diff -u in fixincludes/check.tpl

[Rainer Orth]

While looking at the output of make check in fixincludes, I noticed that
it is in context diff format by default.  I think the unidiff format is
easier to read and generally preferred by the GCC project, therefore I'd
like to propose the following patch.

Ok for mainline?
