    libstdc++: Fix strings read from /etc/sysconfig/clock [PR108530]

    In r13-5339-ge00d5cafbe1a77 I made std::chrono::current_zone() look for
    DEFAULT_TIMEZONE in /etc/sysconfig/clock but that is the wrong variable.
    Old Suse systems use TIMEZONE to determine which zone /etc/localtime is
    a copy of, and old RHEL system use ZONE.

    libstdc++-v3/ChangeLog:

            PR libstdc++/108530
            * src/c++20/tzdb.cc (current_zone): Look for TIMEZONE or ZONE in
            /etc/sysconfig/clock, not DEFAULT_TIMEZONE.=
