Add a sysentvec for CloudABI on x86-64.
Summary: For CloudABI we need to put two things on the stack of new processes: the argument data (a binary blob; not strings) and a startup data structure. The startup data structure contains interesting things such as a pointer to the ELF program header, the thread ID of the initial thread, a stack smashing protection canary, and a pointer to the argument data. Fetching system call arguments and setting the return value is similar to FreeBSD. The only differences are that system call 0 does not exist and that we call into cloudabi_convert_errno() to convert the error code. We also need this function in a couple of other places, so we'd better reuse it here.
