gssd: Don't assume the machine account will be in uppercase

find_keytab_entry() first looks for an entry of the form
<HOSTNAME>$@<DOMAIN>, which corresponds to the Active Directory machine
account.  It assumes that <HOSTNAME> will be in uppercase because that's
how the entry is created if the machine is joined to the domain using
Samba.

But that's not necessarily the case if the another identity management
solution is used... for example a keytab entry for a machine account
created by Centrify will match the actual computer account in Active
Directory, whether that be in upper case, lower case, or mixed case.

So first look for an entry that matches the unmodified hostname and then
convert it to uppercase and try again only if that failed.
