TESTS: don't use deprecated sssd.conf::user option

Currently when SSSD is built '--with-sssd-user=sssd' it's also
configured to run under 'sssd' user by default via sssd.service,
so that sssd.conf::user option is ignored anyway.
Since sssd.conf::user is deprecated and will go away, it doesn't
make much sense to put effort into testing it.
What makes sense is to test sssd.service::User option, but this is
out of scope of this patch.
