adduser fails to find subuid subgid files under /var/lib/extrausers

[Oliver Grawert]

while the patch to support libnss extrausers in adduser and shadow was ported to snappy, there still seem to be some bits missing ... trying adduser on the current 15.04 edge image results in:

useradd: cannot open /var/lib/extrausers/subuid
adduser: `/usr/sbin/useradd --extrausers -d /home/testuser -g testuser
-s /bin/bash -u 1001 testuser' returned error code 16. Exiting.

bug 1475749 seems related here

just touching /var/lib/extrausers/subuid and /var/lib/extrausers/subgid seems to be enough to make this particulare error go away, but it then fails in chfn:

opened bug 1495580 for teh chfn issue, the subuid and subgid issue is fixed for snappy 15.04 already by shipping two empty files

With $ sudo adduser --extrausers testuser I'm no longer getting the "cannot open /var/lib/extrausers/subuid". So I'll mark this one as fixed. I'm getting the chfn error, so let's keep that one.
