[PATCH v2] spufs: use llseek in all file operations

[Arnd Bergmann <arnd@arndb.de>]

The default for llseek is changing, so we need
explicit operations everywhere.

Same as previous version, but no longer breaking the existing llseek
operation in spufs_*box_info_fops. Pushed out to my bkl/llseek branch.
