util/elogtool: add tool to print elog events 

Add a new tool that that prints elog events.
The tool, as input, accepts either a file with the RW_ELOG contents, or
if the file is not provided it reads the contents of RW_ELOG by calling
the "flashrom" tool.

The tool is based on "mosys eventlog list"[1]. For the moment it only
supports "list", but future commits will add additional functionality.

This commit also adds missing ELOG defines needed for the tool. These
defines are added with the rest of the ELOG defines, in
include/commonlib/bsd/elog.h

The tool is placed inside util/cbfstool. The rationale behind the
decision, is that this tool shares a lot in common with the other tools
located in cbfstool: vboot dependency, shared files like common.o and
valstr.o, and in spirit is similar to some of the tools located in
cbfstool/.

As an example, you call the tool like the following:

$ elogtool list -f rw_elog_dump.bin
