unix: add SEEK_* constants on Darwin, FreeBSD, Linux

Browse Source 
The Go "os" package already provides bindings for SEEK_CUR, SEEK_SET and
SEEK_END. Most operating systems also support SEEK_HOLE and SEEK_DATA,
which you can use to skip sparse regions in a file. Let's add bindings,
so we can also do this from within Go.
