[PATCH 15/27] fs-tests: integck: remove trailing backslashes from mount point

[Artem Bityutskiy]

From: Artem Bityutskiy <Artem.Bityutskiy at nokia.com>

The test is not working if the user specified mount point with a trailing
back-slash at the end. Note, this had not worked before my changes as well.
Fix this.
