[PATCH v4 2/4] ci: remove the pipe after "p4 -V" to cache errors

[Jiang Xin <worldhello.net@gmail.com>]

From: Jiang Xin <zhiyou.jx@alibaba-inc.com>

When installing p4 as a dependency, we used to pipe output of "p4 -V"
and "p4d -V" to validate the installation and output a condensed version
information. But this would hide potential errors of p4 and would stop
with an empty output. E.g.: p4d version 16.2 running on ubuntu 22.04
causes sigfaults.

By removing the pipe after "p4 -V" and "p4d -V", we may get a verbose
output, and stop immediately on errors becuase we have "set -e" in
"ci/lib.sh". Since we won't look at these trace logs unless something
fails, so just including the raw output seems most sensible.
