subdir tests: avoid an use of "make -j4", for portability

Otherwise, a spurious failure with Solaris CCS make can be triggered.
The coverage is not actually reduced, since the code path is still
covered when one runs the testsuite with AM_TESTSUITE_MAKE="make -jN"
(as should be done periodically).

* t/subdir-distclean.sh : Call simply "make maintainer-check", not
"make -j4 maintainer-check".
