issue: 4640792 fix incorrect cast

Fix incorrect boolean type definitions for two configuration parameters
that should be integer types based on their actual usage and environment
variable mappings.

The parameters were incorrectly defined as boolean when they should be
integer, causing build failures. This is a follow-up fix to correct the
type mismatches.

Changes:
- performance.polling.yield_on_poll: Change from bool to int
  - Controls number of polling iterations before yielding
  - Disable with 0, not false
- applications.nginx.udp_socket_pool_reuse: Change from bool to int
  - Controls UDP socket pool reuse behavior
  - Disable with 0, not false

These parameters map to environment variables that expect int values:
- XLIO_RX_POLL_YIELD
- XLIO_NGINX_UDP_POOL_RX_NUM_BUFFS_REUSE
