Subject: utils/: add check to ensure severity.db contains all

capabilities

This patch adds a new make target, check_severity_db, to the
utils/Makefile. It greps the severity.db for the presence of each
capability, as computed by the newly abstracted out variable in
common/Make.rules, and issues a build time error if it finds any
missing.

It also silences the check targets, so that only the output from them
will be emitted.
