Bug#307715: dpkg: -l ignores --root, --admindir

[Dan Jacobson <jidanni@jidanni.org>]

Package: dpkg
Version: 1.10.27
Severity: normal

Even though we use --root, --admindir, they are ignored with -l:
$ cd ~/homebrew
$ dpkg --root=. -l|wc
   1693   14722  121212
$ find . -amin -1 -type f
$ dpkg --admindir=./var/lib/dpkg/ -l|wc
   1693   14722  121212
$ find . -amin -1 -type f
$ find . /var/lib/dpkg/  -amin -1 -type f
/var/lib/dpkg/status
/var/lib/dpkg/available
#true, my home brew available file is empty,
$ ls -og var/lib/dpkg

#but we see that even the directories aren't apparently tried:
$ dpkg --root=. -l|wc
