Title: layman/db: Ignore an initially-missing installed file

Avoid:

$ emerge -av app-portage/layman
$ echo 'source /var/lib/layman/make.conf' >> /etc/portage/make.conf
$ layman --fetch
$ layman --list-local

* Warning: an installed db file was not found at: ['/var/lib/layman/installed.xml']

when that's the expected behavior before you've added any local
repositories. Instead, interpret the lack of a local file listing
installed repositories as "no repositories installed" and continue
silently on.
