append2simg: write to temporary file
append2simg causes libsparse to write mmapped data from a file
back to that same file. On btrfs, this sometimes causes a page
of zeroes to be written instead of the file data. Work around
the issue by writing the output to a temporary file and then
renaming it over the original file.
