[PATCH 0/2] Randomize / timestamp trace2 targets

Persistently enabling trace2 output is difficult because it requires specifying a full filename. This series teaches tr2_dst_get_trace_fd() to randomize filenames when a directory or filename prefix are given as targets in the GIT_TR2_* envvars. It also allows expansion of a timestamp template string into the current UTC timestamp.
