Subject: [PATCH] Run ps with an ulimited width on linux

On some systems the output of ps may be truncated, which may prevent
profiles from working as intended.

Some implementations specifically mention that the output width is
undefined "(it may be 80, unlimited, determined by the TERM variable,
and so on)".

This fixes #5226.
