`//pkg/tcpip/link/rawfile` is a package to deal with raw socket and file FDs. It is not only used for Netstack, but rather just generally useful raw file manipulation stuff. This change removes the Unix-error-to-`//pkg/tcpip`-error translation step from its functions; this is now the responsibility of its callers. Callers within Netstack now do the translation by themselves; the translation function is moved to `//pkg/tcpip`. This allows the `//pkg/tcpip/link/rawfile` package to not depend on `//pkg/tcpip`, which in turn means the `//pkg/eventfd` package (which depends on `rawfile`) no longer transitively depends on `//pkg/tcpip`, which in turns means the `//pkg/unet` package (which depends on `//pkg/eventfd`) no longer transitively depends on `//pkg/tcpip`, which in turns means that the `//pkg/eventchannel` package (which depends on `//pkg/unet`) no longer transitively depends on `//pkg/tcpip`, which in turns means that the `//pkg/metric` package (which depends on `//pkg/eventchannel`) no longer transitively depends on `//pkg/tcpip`, which finally means that the `//pkg/metric` package can be used within `//pkg/tcpip`. \o/ This changes does not make it use it, it just moves `rawfile`.
