[aes/pre_syn] Fixed module parameters bug in syn_setup.example.sh

Found bug in hw/ip/aes/pre_syn/syn_setup.example.sh:
- "SEC_" was missing in the name of two module parameter variables (LR_SYNTH_SEC_MASKING and LR_SYNTH_SEC_S_BOX_IMPL)
- This caused that the default module parameters in the RTL files were not overwritten
