ext2simg: fix same_file() to check st_dev
File identity is determined by the combination of st_dev and st_ino, not
by st_ino alone.
This fixes a bug where ext2simg would needlessly make a copy of all the
data when the input and output files happened to have the same st_ino.
Fixes: db6f320912cf ("AOSP: android: add the ext2simg tool")
