Cygwin: passwd/group: store account name case correct

Browse Source 
When looking up valid accounts by name, LookupAccountName returns
a SID and a case-correct domain name.  However, the name was input
and LookupAccountName is case-insensitive, so the name is not
necessarily written the same way as in SAM or AD.

Fix that by doing a reverse lookup on the just fetched SID.  This
fetches the account name in the correct case.  Override the
incoming name with the case correct name from LookupAccountSid.
