[Sergio Schvezov]

Create clickpkg user/group in case it doesn't exist in postinst of ubuntu-snappy-cli

According to https://wiki.debian.org/AccountHandlingInMaintainerScripts

"It should normally not be necessary to cross-check with getent whether an account already exists since adduser --system generally does the right thing. If not, please report a bug against adduser to keep your maintainer scripts simple."

Thus:
sergiusens@lothlorien:~/go/src/launchpad.net/snappy$ sudo adduser --system --disabled-password --home /nonexistent --no-create-home --group clickpkg
Warning: The home dir /nonexistent you specified can't be accessed: No such file or directory
Adding system user `clickpkg' (UID 116) ...
Adding new group `clickpkg' (GID 126) ...
Adding new user `clickpkg' (UID 116) with group `clickpkg' ...
Not creating home directory `/nonexistent'.
sergiusens@lothlorien:~/go/src/launchpad.net/snappy$ sudo adduser --system --disabled-password --home /nonexistent --no-create-home --group clickpkg
Warning: The home dir /nonexistent you specified can't be accessed: No such file or directory
The system user `clickpkg' already exists. Exiting.
sergiusens@lothlorien:~/go/src/launchpad.net/snappy$ echo $?
0

FTR, I took --home /nonexistent from whoopsie's postinst
