The "Client::mds_check_access" expects the target_path without
leading '/' as it eventually calls the "MDSCapMatch::match_path"
which expects the target_path passed to be with out leading '/'
as well.

The single leading '/' was being removed. But absolute path
constructed did have leading '//', so removing all the leading
'/' was necessary.

This causes the clients not to be able to access a particular
path even though it has a rw permission on the specific path.

The patche fixes the leading '//' issue.

This is required to test the features involving
fixes both in client and mds. This is to make
sure the older clients are not broken with the
fix. The version 19.2.2 is used for client.

The test suite sets up the cluster with squid
19.2.2 and upgrades only the ceph cluster node
leaving the client node.

The multifs auth caps bug has a fix both in client and mds.
If it's old client and not patched, we expect that the fs
with 'rw' would end up having 'r' caps with the multifs
auth caps used as in the test
'test_multifs_single_client_cross_access_r_caps_end'.
This patch adds the conditional to validate the same.

The kclient fix isn't yet landed in the kernel and hence
the test 'test_multifs_single_client_cross_access_r_caps_end'
would fail for kernel mount. So disable the failing validation
in the test for kclient.
