Enable build on FreeBSD ports (includes DragonFly BSD)
...
Zstd has been introduced to FreeBSD ports
(http://www.freshports.org/archivers/zstd/ ) which DragonFly BSD also
uses. FreeBSD and DragonFly use the install targets (albeit modified in
some cases) so they must be added to the associated Makefile filters.
