Create a 1 GiB file instead of 1 TiB, because
apparently, on MacOS, the file (sometimes?) is not
created sparse, and fills up users' disks:

On darwin, SEEK_DATA is not the same as on Linux
( 2f8b555de2 )
so use the value provided by the unix package.
This fails at the moment:

Quoting fusefrontend_reverse/node_helpers.go :
// File names are padded to 16-byte multiples, encrypted and
// base64-encoded. We can encode at most 176 bytes to stay below the 255
// bytes limit:
// * base64(176 bytes) = 235 bytes
// * base64(192 bytes) = 256 bytes (over 255!)
// But the PKCS#7 padding is at least one byte. This means we can only use
// 175 bytes for the file name.

Failure is:
# github.com/rfjakob/gocryptfs/v2/internal/nametransform
internal/nametransform/names.go:47:33: undefined: math.MaxInt
math.MaxInt was only introduced in Go 1.17. Use MaxInt32 instead,
which is good enough, even on amd64. It only has to be larger than
any name we might encounter.
Determines when to start hashing long names instead
of hardcoded 255. Will be used to alleviate "name too long"
issues some users see on cloud storage.

When somebody posts "gocryptfs -speed" results, they are
most helpful together with the CPU model. Add the cpu model
to the output.

We used to have "first Translate() wins". This is not deterministic,
as the LOOKUP for the root directory does not seem to reach us, so
the first user LOOKUP would win, which may be on a mountpoint.
