libpayload: multiboot - support meminfo flag
Some simple implementation of the MultiBoot protocol may not pass a
memory map (MULTIBOOT_FLAGS_MMAP missing in the flags) but just the two
values for low and high memory, indicated by the MULTIBOOT_FLAGS_MEMINFO
flag.
Support those kind of boot loaders too, instead of falling back to the
hard-coded values in lib_get_sysinfo().
Tested with a multiboot enhanced version of FILO.
