PT-2538 - fix compatible issues with DBD::MariaDB

[oblitorum]

Sometimes, DBD::MariaDB is more appreciated than DBD::mysql. For example, on a RHEL system, if you setup and install the MariaDB server from official MariaDB mariadb_repo_setup tool, and then you try to install the percona-toolkit package, you’re likely to encounter into an error similar to this:

Because percona-toolkit depends on DBD::mysql, which resolved as perl-DBD-MySQL package on rpm system, which then depends on the mysql-common package. And the mysql-common package is conflict with the MariaDB-common package from the official MariaDB repo. In this case, DBD::MariaDB is preferred for avoiding such conflicts.

In current percona-toolkit (3.7.x), DBD::MariaDB is not regarded at many places, this patch adds the regard and makes an adjustment to the rpm/deb packaging so that perl(DBD::MariaDB) could be a replacement to perl(DBD::mysql), as a dependency.
