make-disk-image: do not use faketime

Browse Source 
Since https://github.com/lkl/linux/pull/394 cptofs preserves the source time,
which is 1970-01-01T00:00:01Z for /nix/store and recent for other files.

This reverts commit f5b3f2c5a7.

# If we don't faketime, we can end up with timestamps other than 1 on the nix store, which
# will confuse Nix in some situations (e.g., breaking image builds in the target image)
# N.B: I use 0 here, which results in timestamp = 1 in the image. It's weird but see
# https://github.com/lkl/linux/issues/393. Also, running under faketime makes `cptofs` super
# noisy and it prints out that it can't find a bunch of files, and then works anyway. We'll
# shut it up someday but trying to do a stderr filter through grep is running into some nasty
# bug in some eval nonsense we have in runInLinuxVM and I'm sick of trying to fix it.
