Pass file descriptor instead of file name
Passing a file descriptor to make_ext4fs_internal() is more flexible.
We can use tmpfile() to create a temporary file.
tmpfile() is better than other solutions because it unlinks the file
right after creating it, so closing fd effectively removes temp file.
Thus we don't have to worry about large temp files accidently left
on the filesystem in case of the program crash.
