also copy files cache verbatim

Browse source 
it seems the file cache does *not* have the ATTIC magic header (nor
does it have one in borg), so we don't need to edit the file - we just
copy it like a regular file.

while i'm here, simplify the cache conversion loop: it's no use
splitting the copy and the edition since the latter is so fast, just
do everything in one loop, which makes it much easier to read.
