interfaces/linux: make dsa special

There used to be specific exemptions carved out for "veth" and "dsa",
which were removed in b8db52bd7c7d ("interfaces/linux: blacklist some
drivers instead of whitelisting"). "veth" was restored in 2958b9d48940
("interfaces/linux: make veth special"). This commit restores the
whitelist for dsa devices as well.
