Issue #3119017 by Gábor Hojtsy, effulgentsia, catch, daffie: Tests fail with MariaDB 10.2.7, but not 10.3.22

// version_compare() treats '-' and '+' as equivalent, and non-numeric

// specifiers. In other words, 10.2.7-MariaDB, 10.2.7+maria, and
// 10.2.7-AnyName are all equal to each other and less than 10.2.7-alpha.
// This means that by appending '-AnyName' for the comparison check, that
// alpha and other pre-release versions of the minimum will pass this
// check, which isn't ideal; however, people running pre-release versions
// of database servers should know what they're doing, whether Drupal warns
// them or not.
