cmd/blsync: use default JWT secret path when datadir is specified

Browse source 
Implements the TODO to automatically use jwtsecret file from the
specified datadir when --blsync.jwtsecret is not explicitly provided.
This matches the behavior of the main geth command and improves UX
by reducing required command line arguments.
