Roger Pau Monné 5e4279a8f3 loader: fix multiboot loading on UEFI ...

The Xen kernel has no symbol tables, so calling lookup_symbol against
it triggers the following Divide by Zero fault:

Loading Xen kernel...
/boot/xen data=0x2809c8+0x149638 |
!!!! X64 Exception Type - 00(#DE - Divide Error)  CPU Apic ID - 00000000 !!!!

Fix lookup_symbol to prevent the #DE fault from happening if the
symbol table is not loaded and also fix loadfile_raw to mark multiboot
kernels as relocatable, since the only multiboot kernel supported is
Xen and was already unconditionally booted as relocatable.
