Statically link legacy provider to evp_extra_test

Like in #17345, evp_extra_test links libcrypto statically, but also has
a dynamic/shared load via the legacy provider, which leads to ambiguous
behavior in evp_extra_test on some platforms, usually a crash (SIGSEGV)
on exit via the atexit handlers.  Statically link the legacy provider to
avoid this.

Fixes #22819
