drm/i915: set O_LARGEFILE in __create_shmem()

Without O_LARGEFILE, file->f_op->write_iter calls
generic_write_check_limits(), which enforces a 2GB (MAX_NON_LFS) limit,
causing -EFBIG on large writes.

In shmem_pwrite(), this error is later masked as -EIO due to the error
handling order, leading to igt failures like gen9_exec_parse(bb-large).

Set O_LARGEFILE in __create_shmem() to prevent -EFBIG on large writes.
