Most exploits don't check nil for generate_payload_exe, they just
assume they will always have a payload. If the method returns nil,
it ends up making debugging more difficult. Instead of checking nil
one by one, we just raise.
See the complaint on #4039. This doesn't fix that particular
issue (it's somewhat unrelated), but does solve around
a file parsing problem reported by @void-in
This looks okay from debug (the host looks like it's generating okay)
but there may be some subtle thing I'm not seeing here. @wchen-r7 can
you glance at this please?
[SeeRM #8498]
According to the Ruby style guide, %w{} collections for arrays of single
words are preferred. They're easier to type, and if you want a quick
grep, they're easier to search.
This change converts all Payloads to this format if there is more than
one payload to choose from.
It also alphabetizes the payloads, so the order can be more predictable,
and for long sets, easier to scan with eyeballs.
