[LTP] [PATCH 1/1] fix ssh03 on system running mls policy

Modified ssh03 to unset TCtmp. On a system running the latest selinux 
mls policy the call to tst_setup in the cmdlib.sh script with the TCtmp 
variable still set with the TEST_USER directory will result in the 
directory being created with the context of the logged in user (i.e. 
administrator running the test 
...staff_u:object_r:home_root_t:SystemLow) when the useradd is run 
afterwords the directory will already exist but the context of directory 
/home/ssh_user3 should be 
user_u:object_r:user_home_dir_t:SystemLow-SystemHigh. Now when the test 
is run to ssh login with the valid password the test will fail due to 
not being able to change to the user directory which is caused by a 
mismatched context. The unset of TCtmp will prevent this. This does not 
appear to be detrimental to systems running with a targeted policy and 
should have no ill affect systems not running selinux, although a test 
could be placed around the unset to determine if selinux is running and 
the mls policy is in use.
