Restore default value for pki_share_db

In commit 22a1b3d the default
values for pki_share_db for non-CA subsystems were changed to
False since subsystems on separate instances will not share the
same database user, but apparently it causes a problem during
TPS installation with a shared instance.

To avoid changing the behavior, the default values have been
restored to True. This param can still be overridden in
pkispawn config as needed.
