clisp testing on linux

[Faré]

Well, CLISP is known for its deterministic but chaotic segfaults (i.e.
sensitive to the slightest perturbation in input), probably due to
some GC bug somewhere, which would explain your failure.

Interestingly, I experience a different failure using GNU CLISP
2.49.60+ (2017-06-25) on NixOS 18.09.1228.a4c4cbb613c, I instead get:
TEST ABORTED:
POSIX:COPY-FILE: illegal keyword/value pair :METHOD, :RENAME in argument list.
The allowed keywords are NIL

This suggests that uiop/filesystem:rename-file-overwriting-target has
bitrotten on the latest CLISP. Any volunteer to fix that in a
backward-compatible way? I'll pass.
