[PATCH 4/4] test: redirect man output to /dev/null

[David Bremner <david@tethera.net>]

In the case the these tests fail, they generate a bunch of output;
this output is not very interesting because it is just the successful
output of a man page. It does however make it hard to see what tests are actually failing, even with NOTMUCH_TEST_QUIET
