[PATCH 4/5] maint: remove last vestiges of 'configure.in' support from the testsuite

[Stefano Lattarini]

* syntax-checks.mk: Don't whitelist any file in the maintainer
check looking against use of 'configure.in' in the testsuite.
* t/autodist-configure-no-subdir.sh: Remove last references to
'configure.in'.
