package/proftpd: add mod_{sql, quotatab} support

- Enables mod_sql which is required for quotatab_sql
- Adds options for enabling mod_quotatab and the sub-component
  file/LDAP/RADIUS/SQL modules
- Copies over ftpquota script if perl and mod_quotatab are
  enabled (This script isn't required but is an additional tool
  for mod_quotatab)
