jemalloc: improve the ptest output

Previouly we only show the output of each text program, actually
each test program includes serveral test cases. Improve the ptest
script to show the output of each test case.

Before:
 # ./run-ptest

 PASS: tests/integration/MALLOCX_ARENA
 PASS: tests/integration/aligned_alloc

After:
 # ./run-ptest
