Fix double-free and broken logic in virt-login-shell

Browse Source 
The virLoginShellAllowedUser method must not free the 'groups'
parameter it is given, as that is owned by the caller.

The virLoginShellAllowedUser method should be checking
'!*ptr' (ie empty string) rather than '!ptr' (NULL string)
since the latter cannot be true.
