Gate setting of ipi_spec_dst on not building for freebsd

some variants of FreeBSD (notably Dells OneFS) implement IP_PKTINFO
partially, and as such the build breaks for those variants.
specifically, it supports IP_PKTINFO, but the in_pktinfo struct has no
defined ipi_spec_dst field.  Work around this by gating the setting of
that variable on not building for FreeBSD

Fixes #23739
