Added TAPE_FILE_ARCHIVE_FILE_ID_FK index

The reponse rate of the CTA catalogue to "eos rm"
commands was too slow.  The response rate was
around 20Hz when using the CTA/EOS production
database configured with 10 database connections.
The rate has now been increased to 30Hz by adding
the TAPE_FILE_ARCHIVE_FILE_ID_FK index.
