libzfs, libzfs_core: send: always write to pipe
By introducing lzc_send_wrapper() and routing all ZFS_IOC_SEND*
users through it, we fix a Linux 5.10-introduced bug (see comment)
This is all /transparent/ to the users API, ABI, and usage-wise,
and disabled on FreeBSD and if the output is already a pipe,
and transparently nestable (i.e. zfs_send_one() is wrapped,
but so is lzc_send_redacted() it calls to ‒ this wouldn't be strictly
necessary if ZFS_IOC_SEND_PROGRESS wasn't strictly denominational w.r.t.
the descriptor the send is happening on)
