Allow console-reading host commands on locked systems
We allow reading the EC console via case-closed debugging on locked
systems, so we should also allow reading it via host command. The
original reason for denying this (EC printing keystrokes) no longer
exists; we don't print keyboard matrix changes by default anymore.
BUG=chromium:479223
BRANCH=none (well, could apply this anywhere...)
TEST=on a system with both hard and soft WP enabled in the EC,
'ectool console' works instead of failing with access denied.
