chromeos-base: Depend on bash when building amd64-host

chromeos-base needs /bin/bash to exist inside the sysroot before it gets
merged, but DEPENDS only includes app-shells/bash when not building the
host packages.  We were lucking out previously due to build orders, but
crrev.com/c/619869 will change the merge order and break this when
re-landed.

BUG=chromium:756240
TEST=Sent to buildbots with crrev.com/c/619869 re-added.
