hooks: add some test about HGPLAIN setting and hooks

In Mercurial 5.7, hooks are now ran with HGPLAIN set, which is a behavior change
in. I could not find explicit test about it so I am adding one. The next
changesets will introduce more change to help user mitigate the behavior change
when needed.

# Disable the $CAP wire protocol capability.

if test -z "$CAP"
then
    echo "CAP environment variable not set."
