fs/pipe: allow sendfile() to pipe again
After commit 36e2c7421f02 ("fs: don't allow splice read/write
without explicit ops") sendfile() could no longer send data
from a real file to a pipe, breaking for example certain cgit
setups (e.g. when running behind fcgiwrap), because in this
case cgit will try to do exactly this: sendfile() to a pipe.
Fix this by using iter_file_splice_write for the splice_write
method of pipes, as suggested by Christoph.
