amd64 U-Boot arch code should be ARCH_X86_64 not ARCH_IA64

When system calls indicate an error they return -1, not some arbitrary
value < 0. errno is only updated in this case. Change all (most?)
callers of syscalls to follow this better, and let's see if this strictness
helps us in the future.

Prefer <elf.h> to the non portable <sys/exec_elf.h>.

ok jca@, deraadt@

Add the u-boot arm64 architecture number and map it to "aarch64" to
match OpenBSD/arm64 MACHINE_ARCH.

ok patrick@

pledge "stdio" after opening up the input & output files.
ok jsg

fstat() of opened fd, rather than stat(), to avoid TOCTOU
ok jsg

Correctly handle files smaller than an ELF header; reported by drahn@bitrig

Improve mkuboot's ELF handling. This fixes the problem where mkuboot
running on 64-bit systems does not create valid images.
While there, append kernel symbols at the end of the kernel.

ok syl@

Let mkuboot recognize native ELF binaries and only output the program headers
area in this case, to save the need for `objcopy -O binary'; this will make
beagle install/upgrade processes easier until they get a native bootloader.
Tested by florian@ on panda ES and rapha@ on BeagleBone

Move mkuboot to the proper location.
