build: respect Automake silent-rules when generating hello.1

[Collin Funk]

This patch makes './configure --enable-silent-rules' print:

    $ make
    [...]
    AR       lib/libhello.a
    CCLD     hello
    GEN      hello.1

Instead of:

    $ make V=0
    AR       lib/libhello.a
    CCLD     hello
    /bin/sh '/home/collin/.local/src/hello/build-aux/missing' help2man 
--include=./man/hello.x ./hello -o hello.1-t
    chmod a=r hello.1-t
    mv -f hello.1-t hello.1
