James Clark 33ce9fc4f8 perf test: Add option to change objdump binary
All of the other Perf subcommands that use objdump have an option to
specify the binary, so add the same option to 'perf test'.

This is useful if you have built the kernel with a different toolchain
to the system one, where the system objdump may fail to disassemble
vmlinux.

Now this can be fixed with something like this:

  $ perf test --objdump llvm-objdump "object code reading"
