testsuite: Specify metrics collected by T17516

Previously it collected everything, including "max bytes used". This is
problematic since the test makes no attempt to control for deviations in
GC timing, resulting in high variability. Fix this by only collecting
"bytes allocated".

(cherry picked from commit f1088b3f31ceddf918a319c97557fb1f08a9a387)
