tests: improve SEEK_DATA test for MacOS

(1)

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:

https://github.com/rfjakob/gocryptfs/issues/625

(2)

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