Omar Sandoval 32c0ce9f0d libdrgn: orc_info: don't assume ORC section alignment 
ORC sections do seem to be aligned as we expected in vmlinux, but not in
kernel modules (the kernel's module loader takes care of aligning it
properly regardless of the ELF section alignment). This causes stack
tracing to fail when the stack trace contains a frame in a kernel module
without DWARF, e.g., vmx_do_nmi_irqoff in arch/x86/kvm/vmx/vmenter.S.

Fix it by going back to copying instead of assuming alignment.
