Does not compile with MariaDB client libraries

[smokey42]

The latest release fixes compatibility with MySQL 5.6/5.7 but breaks compatibility with MariaDB >= 10.0.0.

IMHO the line in question is

oursql/oursqlx/_exceptions.c

Line 620 in 0488d1d

#if MYSQL_VERSION_ID >= 50700

Compiling on Alpine Linux (which does only have MariaDB):

This problem also appears to happen when you pip install oursql on debian stretch (which uses libmariadbclient-dev for mysql.h).
