Bug#87323: apt: apt-get tries to open etc/apt/sources.list

[<herbert@gondor.apana.org.au>]

Package: apt
Version: 0.5.0
Severity: normal

Running apt-get update where `pwd` != / gives
E: Opening etc/apt/sources.list - ifstream::ifstream (2 No such file or directory)

Running it under / works correctly.
