gen_nodes/gen_hosts: fix recursive loop and template errors in sysbench

The sysbench workflow had multiple template resolution issues:

1. "Collect dynamically supported filesystems" task was causing a
   recursive loop due to using 'vars' which includes all variables
   in the current context, including 'sysbench_enabled_filesystems'
   that the task is trying to set.

2. Subsequent tasks using 'vars' in template loops were getting
   "CapturedExceptionMarker" errors when trying to concatenate
   lists, due to template resolution failures.

3. Missing | list filters in map() chains were causing template
   evaluation errors.

Fix this by:
- Using 'hostvars[inventory_hostname]' instead of 'vars' to avoid
  circular references in all sysbench-related tasks
- Adding | list filters to ensure all map() operations return lists
- Renaming local variables consistently across both roles

This affects both gen_nodes and gen_hosts roles that have identical
problematic task patterns.

Fixes: 8da9287 ("workflows: add new sysbench workflow with MySQL
support with fs support")
