MySQL/MariaDB version strings may have suffixes which may contain dots;
for instance, Debian stretch has 5.5.5-10.1.37-MariaDB-0+deb9u1 or
such. Therefore, we make the version extraction more liberal, and only
require that there are at least three parts separated by dot, and
ignore additional parts.
We also fix an erroneous test expectation, which would be triggered on
CI now, right away. This patch has been provided by petk@.

# Running the tests:
# (Note: Doesn't work currnetly on HEAD, see:
# http://news.php.net/php.qa/64378)
#
# PDO_MYSQL_TEST_DSN - DSN
# For example: mysql:dbname=test;host=localhost;port=3306
#
# PDO_MYSQL_TEST_HOST - database host
# PDO_MYSQL_TEST_DB - database (schema) name
# PDO_MYSQL_TEST_SOCKET - database server socket
# PDO_MYSQL_TEST_ENGINE - storage engine to use
# PDO_MYSQL_TEST_USER - database user
# PDO_MYSQL_TEST_PASS - database user password
# PDO_MYSQL_TEST_CHARSET - database charset
#
# NOTE: if any of PDO_MYSQL_TEST_[HOST|DB|SOCKET|ENGINE|CHARSET] is
# part of PDO_MYSQL_TEST_DSN, the values must match. That is, for example,
# for PDO_MYSQL_TEST_DSN = mysql:dbname=test you MUST set PDO_MYSQL_TEST_DB=test.
