ipa-replica-install: nsds5replicaUpdateInProgress is a Boolean

nsds5replicaUpdateInProgress is defined in LDAP schema as a boolean.
Now that IPA API is able to properly map booleans to the python
bool type, this attribute is not a string any more and
comparisons can be done directly based on its real type.

The code in ipa-replica-install was reading nsds5replicaUpdateInProgress
and calling value.tolower() == 'true' but should now use
value == True instead.
