Subject: [PATCH] Recognize receive|recv output for -u detection

zfs help output on FreeBSD 11.2-STABLE:

	receive|recv [-vnsFu] <filesystem|volume|snapshot>
	receive|recv [-vnsFu] [-o origin=<snapshot>] [-d | -e] <filesystem>
	receive|recv -A <filesystem|volume>

we should detect -u in the same way we try it for -x
