Install nbd explicitly (#87)

This pull request includes changes to the installation scripts for CentOS, Fedora, and Debian/Ubuntu systems to ensure the necessary packages are installed. The most important changes include adding the `nbd` package to the CentOS/Fedora installation and the `nbd-client` package to the Debian/Ubuntu installation.

Package additions:

* [`scripts/install-elastio.sh`](diffhunk://#diff-140ec7e3534c5f069e64278e6e34535630189b72153533b35375b20dd166f5ceR68): Added `yum install -y nbd` to the `cent_fedora_install()` function to ensure the `nbd` package is installed on CentOS and Fedora systems.
* [`scripts/install-elastio.sh`](diffhunk://#diff-140ec7e3534c5f069e64278e6e34535630189b72153533b35375b20dd166f5ceL155-R156): Added `apt-get --no-install-recommends install -y elastio ntfs-3g nbd-client` to the `deb_ubu_install()` function to ensure the `nbd-client` package is installed on Debian and Ubuntu systems.
