Fix nft_rtpengine compilation on RHEL/AlmaLinux 9.x kernel 5.14

Add support for RHEL/AlmaLinux/Rocky Linux 9.x kernels which backport
the 'reset' parameter to nft_expr_dump function from kernel 6.2.0.

This affects all RHEL 9 family distributions with kernel 5.14.

Tested on AlmaLinux 9.7 with kernel 5.14.0-611.11.1.el9_7.x86_64
