kexec-tools: Fix option/argument parsing

The argument parsing is currently a bit broken as main()'s getopt_long()
knows nothing about either the architecture-specific options or, even
more specifically, the architecture-and-loader-specific options.

This patch introduces new #defines for all architectures,
KEXEC_ALL_OPTIONS and KEXEC_ALL_OPT_STR.  These contain all possible
options for a given build, and the getopt_long() passes in main() and
arch_process_options() will now recognise arch- and loader-specific
options; these will not be re-ordered in argv[], there is no confusion
over which argv[] entry is the kernel filename, and using '--opt=foo' and
'--opt foo' both work.

All architectures have command line options (and #define OPT_BLAHs)
consolidated into their include/arch/option.h files.  x86_64 builds
parts of i386/ as well, so now both share a single option.h file (with
a symlink).
