LibELF+Kernel: Validate program headers in Image::parse

Browse source 
This should catch more malformed ELF files earlier than simply
checking the ELF header alone. Also change the API of
validate_program_headers to take the interpreter_path by pointer. This
makes it less awkward to call when we don't care about the interpreter,
and just want the validation.
