[LTP] Remove pidns14 test case

["M. Mohan Kumar" <mohan@in.ibm.com>]

[PATCH] Remove pidns14 test case
Container-init may be immune to unhandled fatal signals (like SIGUSR1)
even if they are from ancestor namespace. SIGKILL/SIGSTOP are the only
reliable signals to a container-init from ancestor namespace. So remove
test case pidns14 from container test suite. Please check git commit id
b3bfa0cba867f23365b81658b47efd906830879b for the kernel changes.

-* * 	$ Where init has not defined a custom handler for USR1
-* * 	$ Should kill the container
-* * 	$ else the test fails.

-* * Description:
-* *  This testcase creates container and waits till it is awakened by parent.
-* *  The parent process sends the SIGUSR1 to container init.
-* *  This would invoke default handler & terminate the container init.
-* *  In parent process verify, if the SIGUSR1 signal is passed to c-init.
-* *  If yes then Test is Passed else Test is Failed.
