Patch createdb script to avoid race condition / file tampering
During the initialization net/rtg uses the /tmp/mysql.sql
and /tmp/rtg.sql to store the SQL commands executed in the
database with special user privileges.
Using well known files can lead to a race condition between
two process who uses the same file names and allow file
tampering by a malicious user.
This fix uses mktemp command to create temporary files
in a safe way
