Update to rra-c-util 5.5 and C TAP Harness 3.1

Update to rra-c-util 5.5:

* Use Lancaster Consensus environment variables to control tests.
* Use calloc or reallocarray for protection against integer overflows.
* Suppress warnings from Kerberos headers in non-system paths.
* Assume calloc initializes pointers to NULL.
* Assume free(NULL) is properly ignored.
* Improve error handling in xasprintf and xvasprintf.
* Check the return status of snprintf and vsnprintf properly.
* Preserve errno if snprintf fails in vasprintf replacement.

Update to C TAP Harness 3.1:

* Reopen standard input to /dev/null when running a test list.
* Don't leak extraneous file descriptors to tests.
* Suppress lazy plans and test summaries if the test failed with bail.
* runtests now treats the command line as a list of tests by default.
* The full test executable path can now be passed to runtests -o.
* Improved harness output for tests with lazy plans.
* Improved harness output to a terminal for some abort cases.
* Flush harness output after each test even when not on a terminal.
