Correct man page generation

[bunder2015]

Description

Some man pages were left out of the makefile due to a missing backslash

Motivation and Context

Missing man pages which are present in git clones but missing from release tarball and make outputs #6409

Release tarball will need to be regenerated after merging

That would explain it. I've created an 0.7.1 project we can use to track these fixes.

I guess this is being dealt with in #6411

@bunder2015 no need to close this, I'll merge it shortly. #6411 was opened against the zfs-0.7-release branch and this commit against master since we need it on both branches.
