MySQL or Mariadb interrupts Reva build.

[MahdiBaghbani]

Reva makefile run tests while building reva and TestGetShare/empty_list requires binding to local port 3306, which is a well known port for MySQL and MariaDB.

It would be nice to change this port for testing or include it on Install docs in the README file at root.
