Test cleaning up unreadable temporary test directory

Neither the new nftw()-based rm_rf() implementation, nor the fallback
implementation, should fail the test if there is an error during cleanup
of the directory tree. And the output on stderr that the nftw()-based
implementation emits should not interfere with Meson parsing the TAP
stream on stdout.

The test is run in a subprocess so that we can clean up after ourselves.
