src.ctf.lttng-live fix: remove overly strict check for session name

The live component checks that the path of a stream contains a
session's name. While this check works when interacting with pre-2.11
peers, there is no reason for a session's name to necessarily be in a
stream's path.

The LTTng relay daemon, as of 2.11, now expresses its path relative to
a session's output path, the session's name no longer appears in a
stream's path.

There are no comments explaining the reason for this check and it is
not present in babeltrace 1.5.x. Hence, it appears safe to remove it.
