Commit8d56108ffbmoved this function from the generic (no build-tags) fileutils.go to a unix file, adding "freebsd" to the build-tags. This likely was a wrong assumption (as other files had freebsd build-tags). FreeBSD's procfs does not mention `/proc/<pid>/fd` in the manpage, and we don't test FreeBSD in CI, so let's drop it, and make this a Linux-only file. While updating also dropping the import-tag, as we're planning to move this file internal to the daemon.
