tests: Add code coverage

We want to be able to measure code coverage for our test cases. This
patch adds initial support for measuring the coverage of all of the
files in the repo when running the test cases.

Simply run:
    `make check-code-coverage`
and an lcov report will be generated

NOTE: This doesn't yet add any filtering to throw out the results for
system headers and tests cases, but the list of results isn't long so it
is easy to see the relevant coverage results and we don't want to add
any false negatives.

Tested:
    Sdbuplus plus still builds fine without the code coverage utilities
    by default. sdbusplus now builds with `./configure
    --enable-code-coverage` and corrects the libs and cflags accordingly
    to enable coverage. Make then succeeds to generate a report when run
    with `make check-code-coverage`
