Workaround authselect issue in F28AW

For beta we are seeing an issue where the nsswitch.conf file
is getting the altfiles entry removed from it by authselect.
As a hack workaround let's make anaconda not call authselect
by default by removing the fprintd-pam rpm from the ostree.

See the following for context:
