stack: Simplify argument parsing. Don't use dwfl_standard_argp.
We were using dwfl_standard_argp but trying to add our own and substract
some options from it. dwfl_standard_argp also handles kernel, modules,
executables without state and process maps that stack doesn't support.
That made argp parsing somewhat ugly and meant our --help and --usage
didn't really match. Just handle the dwfl_standard_argp options we do
want directly ('-p', '--core', '-e' and '--debuginfo-path'). That way
we can also do sanity checking on the options given.
