containers/ltp: Remove tests dependent on loop devices

[anoopcs9]

We have noticed failures in several recently added tests due to a missing loop device on the client (VM) machine. See below for an example:

run_ltp.sh: /opt/ltp/testcases/bin/chdir01
tst_buffers.c:57: TINFO: Test is using guarded buffers
tst_tmpdir.c:316: TINFO: Using /testdir/LTP_chdQCZGxn as tmpdir (unknown filesystem)
tst_device.c:97: TBROK: Could not stat loop device 0

Summary:
passed   0
failed   0
broken   1
skipped  0
warnings 0

For the time being, we remove those tests until we know the actual requirement for loop devices while running them.
