* debian/control: Update/improve the build dependencies (Closes: #1040582)
- enable libkeyutils-dev also on ia64, as it is available there as well
- enable libjudy-dev, libxxhash-dev, and libglvnd-dev on all the
architectures, as they are not specific to a certain OS
- switch the build dependencies that exist only on Linux from
"!hurd-i386 !kfreebsd-i386 !kfreebsd-amd64" to "linux-any":
libkeyutils-dev, libapparmor-dev, apparmor, libaio-dev, libcap-dev,
libsctp-dev, libatomic1, libkmod-dev, libgbm-dev
