Revert "mariadb 10.1.15"

Apparently, mariadb 10.1.15 was "never released". Upstream have yanked the
tarball off their servers completely, despite the release notes still being
available noting 10.1.15 was a "stable (GA) release". Who knows.
The next release is scheduled to be 10.1.16.

This reverts commit 1fb94a082f.
