Title: id: fix segfault on linue

`id -P` currently segfaults on linux.

$ build/id -P
Segmentation fault

The problem is the incorrect memory layout of common::c_passwd (struct passwd),
and subsequent dereferencing of invalid pointers in id.rs/pline()/from_cstr().

This is only tested on Linux i hope i haven't messed up the MacOS paths.
