Copy only the sections we need -- various compiler versions add various extra sections. In particular, the .note.gnu.property section can precede .text, ruining the entry point.

Tested on Debian trixie with GCC 14.2.0 and Fedora 40 with:

qemu-system-i386 -bios cpu/x86/pc/emu/build/emuofw.rom -serial stdio

This might be broken on other platforms too -- I didn't check.
