[LTP] PATCH : test_fs_bind testscript for busybox machines

Hi,

The test_fs_bind testscript hangs indefinitely when run on a machine 
where busybox applets are used.

The test hangs while trying to restore the mounts after a test run.


This happens because the "xargs" applet from busybox doesn't understand 
the --max-args=1 option. Thus, the mounts from the test are not removed 
and this goes on in a loop, indefinitely.

This could be avoided by using "-n" option which is supported by both 
the implementations of xargs.


Attached the patch here.

Thanks

Suzuki
