Remove misleading "pipe" utility and test

Browse Source 
If a "cat" tool as simple as the removed one is needed, it should be
implemented with Goa, only depend on libc/posix (*not* base), and be
named "simple_cat". Up to today, the misleading naming of the removed
tool, tricked me into believing "test-pipe" tests POSIX pipes, which it
did not!

The pipe utility is for piping between files using the
semantics of POSIX stdio.
An example of piping clock jitter to a terminal session:
! <start name="pipe">
! <resource name="RAM" quantum="2M"/>
! <config>
! <vfs>
! <jitterentropy name="rng"/>
! <terminal name="tty"/>
! </vfs>
! <libc stdin="/rng" stdout="/tty"/>
