t/aggregate-results: accomodate systems with small max argument list length

IRIX 6.5 has a default maximum argument list length of 20480.  The file
glob that is passed to aggregate-results currently exceeds this length, and
so the script cannot run successfully.  Work around this issue by passing
the file names in via the standard input rather than the argument list.
