diagnostics: add cros_healthd user to the disk group

cros_healthd reports the size of non-removable block
devices on the system. To get this information, cros_healthd
needs to send ioctls to various /dev nodes, all of which
are only accessible by either root or the disk group.

BUG=b:128683357
TEST=ran build_packages and build_image for nami, deployed to
a DUT and checked grep disk /etc/group, made sure cros_healthd
was a member.
