LU-7483 test: Modifying filtering in acl for SElinux feature

With SElinux feature enabled on Client, sanity.sh test_103a failed
with 'Host key verification failure'. "ls -l" command was producing
'.' at the end to indicate extra security attributes when SElinux is
is enabled.

Hence, modifying filtering by not allowing '.' in the output. Files
modified are as follows: cp.test, misc.test, permission.test,
setfacl.test, 974.test, 4924.test .
