net-analyzer/nload: don't compress the man-page

As pointed out by @mgorny [1], packages should not compress their man pages on their own.
Instead, Portage needs to handle the compression.
Currently, `ecompressdir` is smart enough to recompress the man-pages as needed.
However, this is not a fully PMS-compliant behavior.

So, patch the Makefile.am not to compress the man-page.
A corresponding pull request is submitted upstream [2].

+Subject: [PATCH 1/1] Makefile,spec: don't compress the man-page
+
+Package managers like to compress man-pages on their own,
+because the type of compression for man-pages is user-configurable.
+In particular, Gentoo [1] doesn't want packages to compress their man-pages.
+Gentoo Portage has workarounds for this,
+but this is not specified in Package Manager Specification and
+results in extra compression-decompression pass.
+
+RPM also compresses man-pages itself (in `brp-compress`)
+(and similarly recompresses them as needed)
+rather than relying on packages to install compressed man-pages.
+
+Automake can handle installation of man-pages without the explicit "install" target,
+so use the standard automake-provided way of installing man-pages.
+It's also smart enough to package `nload.1.in` automatically.
+
+Don't specify an explicit man-page extension in .spec file as recommended by Fedora.
