LU-16661 build: remove -dev packages for Debian

Don't depend on libmount-dev, libsnmp-dev, libkeytils-dev for the
lustre-client-utils and lustre-server-utils packages.  These are
only needed for build and for the lustre-client-dkms package.

Disable SNMP by default as this is no longer used anywhere.

Fixes: af2f77633b ("LU-13818 build: use libsnmp-dev instead of libsnmp30")
