MDEV-28782: modify mariadb-tzinfo-to-sql to set 'wsrep*' variables ap…

…propriately in cases where Galera is not compiled in

In 3b662c6, it was discovered that the
values of the 'wsrep_is_on' and 'wsrep_cannot_replicate_tz' variables need
to be overridden for embedded builds to pass

However, there are other build configurations where these variables also
have NULL values.  The mariadb-tzinfo-to-sql script (implemented in
sql/tztime.cc) can be slightly modified to set its 'wsrep_is_on' and
'wsrep_cannot_replicate_tz' variables more predictably in all such cases,
thus allowing the mysql_tzinfo_to_sql_symlink.test test to pass without
any special-casing for particular build types.
