[Buildroot] [PATCH] board/pc/post-build.sh: fix typo in grub boot.img path

[Thomas Petazzoni]

Commit 3468ef16fa55610bae3bacefaf816231a20cfab0
("configs/pc_x86_64_efi: use genimage GPT partition table support")
had a small typo on the path to grub boot.img file: i387-pc instead of
i386-pc, which causes a build failure.

Fixes:
