perf test: Enhance the LLVM tests: add kbuild test



This patch adds a kbuild testcase to check whether kernel headers can be
correctly found.

For example:
  # mv /lib/modules/4.3.0-rc5{,.bak}
  # perf test LLVM

    38: Test LLVM searching and compiling                        : Skip

  # perf test -v LLVM
  ...
  <stdin>:11:10: fatal error: 'uapi/linux/fs.h' file not found
  #include <uapi/linux/fs.h>
          ^
  1 error generated.
  ERROR:	unable to compile -
  Hint:	Check error message shown above.
  Hint:	You can also pre-compile it into .o using:
     		 clang -target bpf -O2 -c -
	 with proper -I and -D options.
  Failed to compile test case: 'Test kbuild searching'
