fix(rootless): actually create the docker install user

Browse Source 
useradd was missing its login-name argument (and -m), so it failed — silently,
because local result=$(...) swallowed the exit code and checkSuccess reported
success. The rootless install user was therefore never created, which cascaded
into 'invalid user dockerinstall' and a daemon that never came up. Pass the
username + -m (subordinate uid/gid ranges come from login.defs), unmasked.
