libstdc++: Use /etc/sysconfig/clock for std::chrono::current_zone() [PR108530]

On some systems /etc/localtime is a tzfile, not a symlink to one. We
cannot use it to determine the current time zone in that case. See if
/etc/sysconfig/clock sets the variable DEFAULT_TIMEZONE instead.

libstdc++-v3/ChangeLog:

PR libstdc++/108530
* src/c++20/tzdb.cc (current_zone): Look for DEFAULT_TIMEZONE in
/etc/sysconfig/clock.
