[FYI] {master} build: fix cleaning of test directories in contrib (and in t/perf)

[Stefano Lattarini]

* Makefile.am (clean-local-check): Update recipe to cater to the fact
that some tests using a temporary directory have been placed in other
directories that the 't/' directory (for the moment, at least 't/perf'
and 'contrib/t').
