Small patch to fix a segfault in cgget when it is invoked as
follows:
        cgget CgName

This particular invocation wasn't being tested, so I added a
simple functional test to ensure basic functionality.

Code is available here:
https://github.com/drakenclimber/libcgroup/tree/issues/38

Tests are available here:
https://github.com/drakenclimber/libcgroup-tests/tree/issues/38

Automated tests are passing and results are here:
https://github.com/drakenclimber/libcgroup/runs/2345425112

Code coverage remained the same at 51.0%.  I verified
the new logic is being exercised by the functional
tests:
