This change takes some pieces from MariaDB, including compat_ssl.h and
changes in my_md5.cc.
MySQL utilizes FIPS_mode() and FIPS_mode_set() functions that are not
available in OpenSSL 3.x any more. This patch only mocks the call of
those functions, returning 0 every time, which effectively makes usage
of those functions non working. For making the MySQL build with
OpenSSL 3.x this seems to be enough though.
