windows: Fix relocation sections generation during module conversion from PE to ELF

The commit 98ad84328 (kern/dl: Check for the SHF_INFO_LINK flag in
grub_dl_relocate_symbols()) revealed a bug in the code converting PE
module images to ELF files. The missing SHF_INFO_LINK flag for SHT_REL
and SHT_RELA sections lead to hangs during GRUB load. This only happens
for the GRUB images generated on Windows platforms. The *NIX platforms
are not affected due to lack of PE to ELF conversion step.

This patch fixes the issue...
