Subject: [PATCH] tests: don't consider "make check" a compiler error
In a number of places, the output format from "make check" is
incorrectly interpreted as compiler warning output (triggered by
the presence of colons and parenthesis in the output). Convert
these lines to similar output that does not trigger false build
warnings.
In the case of the tst_uuid.c program, the "ctime()" output was
difficult to change, but in fact it is better to actually compare
the time-based UUID against wallclock time instead of just printing
the formatted time as a string, so this test is improved.
