[LTP] [PATCH] syscalls/pipe08: Rewrite test using new LTP API

[Cyril Hrubis]

Hi!

I've changed this to volatile int in order to avoid miscompilation and
pushed, thanks.

Side note, anything that is changed asynchronously from a signal handler
is better to be declared volatile in order to avoid compiler from
assuming it's value, as the compiler does not understand that execution
flow can jump into a signal handler.
