[bug#34351] [PATCH] gnu: mariadb: Fix build

[Nikolai Merinov]

The mariadb package failed to build starting from 2019-01-01. The reason for
this failure is the hard-coded "2018-12-31 21:01:23" event execution time in
the mysqldump.test. If we try to run this test after a hard-coded time then
test fails with next additional message in test log:
> +Warnings:
> +Note   1588    Event execution time is in the past and ON COMPLETION NOT 
> PRESERVE is set. The event was dropped immediately after creation.

* gnu/packages/databases.scm (mariadb): Change an event execution time in
  mysqldump test to the future time.
