generic: test lseek with seek data mode on a one byte file
Test that seeking for data on a 1 byte file works correctly, the returned
offset should be 0 if the start offset is 0.
This is a regression test motivated by a btrfs bug introduced in kernel
6.1, which got recently fixed by the following kernel commit:
2f2e84ca6066 ("btrfs: fix off-by-one in delalloc search during lseek")
