[clang-format] [NFC] keep clang-format tests clang-format clean

[MyDeveloperDay]

Summary

I use several of the clang-format clean directories as a test suite, this one had got slightly out of wack in a prior commit

[HazardyKnusperkeks]

Why is the file mode changed? As far as I know this makes the file executable? (Disclaimer: I'm a primarly windows user.)

change the mode back

clang/unittests/Format/MacroExpanderTest.cpp

for (size_t I = 0, E = Tokens.size(); I != E; ++I) {
       EXPECT_EQ(Tokens[I]->MacroCtx->StartOfExpansion, Attributes[I].Start)
           << Context << " in " << text(Tokens) << " at " << File << ":" << Line;
       EXPECT_EQ(Tokens[I]->MacroCtx->EndOfExpansion, Attributes[I].End)
           << Context << " in " << text(Tokens) << " at " << File << ":" << Line;
       EXPECT_EQ(Tokens[I]->MacroCtx->ExpandedFrom, Attributes[I].ExpandedFrom)
           << Context << " in " << text(Tokens) << " at " << File << ":" << Line;
     }
