Subject: [PATCH] Build/Test Tools: Use a non-zero exit code in
 `wp_check_php_mysql_versions()` when minimum PHP or MySQL requirements are
 not met.

This allows automated scripts and test suites to interpret the result correctly.

Props jrf, spacedmonkey.
Merges [45350] to the 5.2 branch.
Fixes #47169.
Built from https://develop.svn.wordpress.org/branches/5.2@45351
