feat: append socket path to resurrect_dir

BREAKING: will break existing sessions,
since session save location is changed.

Supposed migration path (to be tested):
while Tmux is running, remove previous version of resurrect
(remove from Tmux conf & TPM uninstall), then install this version,
then save your session.
