Installation requires user name and it group name to be the same

Build tested: 1.0.7-1

For Suse 12, when creating an user (i.e. guest), the user belongs to the users group by default. Files would have ownership as, in the case of my tests, guest:users. The following commands in the post-install script would fail due to group does not exist.

guest@linux-p7qp:~/mariadb/columnstore/bin> cat post-install |grep chown
chown -h $user.$user *.so >/dev/null 2>&1
chown -h $user.$user libstdc++.so.6 >/dev/null 2>&1
$SUDO chown $user:$user $installdir/etc/Columnstore.xml

As a result, incorrectly ownership would be set for the files and ColumnStore would failed to startup.

The fix would be modifying the above commands to change user name only, and leaving group name as it.

I don't know where else in the source code also have this issue, if any and I don't know if there are other issues relating to this. When I created the user guest and assigned it to the guest group, the same installation was successful.

We did hit this issue previously because for Centos and Debian, creating a user would default to a group with the same name. Also, the root user also beings to the root group.
