[clang-format][tests] Explicitly specify style in some tests

[r.stahl]

Summary

This fixes broken tests when doing an out-of-source build that picks up a random .clang-format on the file system due to the default "file" style.

This should be trivial enough to just commit, but I'd just be more comfortable if someone looked at it before, because this is my first commit in this area of clang.

What's wrong with -style=llvm?

I looked at all the tests in that folder and saw that LLVM is the more common usage and unified it.

test/Format/adjust-indent.cpp

-// RUN: grep -Ev "// *[A-Z-]+:" %s | clang-format -lines=2:2 \
+// RUN: grep -Ev "// *[A-Z-]+:" %s | clang-format -style=LLVM -lines=2:2 \
 // RUN:   | FileCheck -strict-whitespace %s
 
 void  f() {
 // CHECK: void f() {
 int i;
 // CHECK: {{^  int\ i;}}
  int j;
 // CHECK: {{^  int\ j;}}
 }

test/Format/disable-include-sorting.cpp
