Using -ef to check for the same file is nicer than relying on a magic
symlink-to-fakedate.
Notice that -ef isn't stricly posix (but supported by bash/dash/zsh), so
I've changed the shebang to /bin/bash.
While we are at it, restructure the logic to do a single exec at the end
instead of handling the epoch/!epoch cases differently for simplicity.
With that out of the way we can directly install it as $HOST/usr/bin/date
instead of the fakedate / date symlink.
