xfstests: test 205, test writing to ENOSPC

Use larger files and different writing styles to fill a 100MB filesystem
to being full. In each case we should get very close to the filesystem
being full before getting ENOSPC. This tests different types of ENOSPC
failures to test 203 and requires more changes to pass.
