Dylan Reid d48d1dcd3d vmm: export full setup-header area for x86_64 kernels ...

The Linux x86 boot protocol defines the setup area as
(setup_sects + 1) * 512 bytes. Previously we exported only the
boot_params buffer (4096 bytes), which is wrong for kernels with
setup_sects >= 8 where the actual setup area exceeds boot_params.

Truncate or extend the existing buffer to the correct setup_sects-
derived length, reading any extra bytes directly from the kernel file.
This avoids an extra allocation in the common case (setup_sects <= 7)
and matches QEMU's fw_cfg_add_kernel() behavior in
hw/i386/x86-common.c.
