Subject: [PATCH] Link portability/error.c with mtr-packet when missing on
 MacOS

Change 817f171d broke the MacOS build.

Change 817f171d converted the error reporting in mtr-packet from
perror() to error().  That's fine, but error() is missing on MacOS.
We already had portability/error.c for this reason, but that was
previously only linked into the mtr binary, not mtr-packet.

This change also links portability/error.c with mtr-packet, when
error() is missing from the OS.
