Make the "info proc" documentation more consistent.

Remove "running" in a few places since "info proc" can be used with
core dumps as well as running processes on both Linux and FreeBSD.

Use "the specified process" in the description of most "info proc"
subcommands.

Use "additional information" instead of "/proc process information" in
the "info proc" description to more closely match the language in the
manual.
