Original change's description:
> [starnix] Make exec_binary tests not panic
>
> These gvisor tests for exec dynamically create an ELF which has several
> weird properties:
>
> 1. The alignment field is 0, which causes a divide by zero in the elf
>    parser. Fix the elf parser to accept this.
> 2. The elf wants to be mapped at address 0x40000, which is lower than
>    zircon will go. This causes an unrecoverable error in starnix exec,
>    which previously meant a starnix panic. Fix starnix to terminate the
>    process with SIGSEGV instead of panicking. (The panic predates the
>    signal handling code in starnix.)
