tasks/upgrade-locale-utf8-syntax: new testcase

When system's locale changed e.g. from en_US.utf8 to en_US.UTF-8,
older PostgreSQL versions were unable to upgrade the data
directory.  From Fedora 20 we should be able to upgrade without
issues.

Related: #1007802

* lib_pgsql.sh (dtf_postgresql_cb_upgrade)
(dtf_postgresql_cb_upgrade_select): New callbacks for
dtf_postgresql_upgrade_tour function.
(dtf_postgresql_upgrade_tour): Function determining against which
data the installation is able to upgrade and performs all the
possible upgrade scenarios.
* tasks/upgrade-basic/runtest.sh: Switch to
dtf_postgresql_upgrade_tour usage.
* tasks/upgrade-utf8-syntax/config.sh: New testcase config.
* tasks/upgrade-utf8-syntax/runtest.sh: New testcase.
