Parsing runc.conf results in duplicate values #2727
Description
When evaluating a configuration file specified via RPC (e.g., runc.conf), CRIU will parse this config file twice:
Line 332 in 5c2f02b
Line 784 in 5c2f02b
This causes options such as --action-script to accumulate duplicate values, leading to unexpected behavior (e.g., when used with criu-coordinator).
