[committed] libstdc++: Fix bootstrap failure with --enable-vtable-verify [PR118981]

[Jonathan Wakely]

The compiler emits code with init_priority(99) for -fvtable-verify=std
and that creates a section conflict with the uses of init_priority(99)
that I recently added to src/c++20/tzdb.cc.

Change tzdb.cc to use a different priority to avoid the conflict.

libstdc++-v3/ChangeLog:

        PR c++/118981
        * src/c++20/tzdb.cc: Use init_priority(98) instead of
        init_priority(99).
---

Tested x86_64-linux, and bootstrapped with --enable-vtable-verify.

Pushed to trunk.
