A refused binary import leaves its stub directory in the temp dir #3485
Description
ae build (and ae run) of a program with a binary import writes the import stubs to $TMPDIR/ae-binimport-<pid>-<n> (tools/ae.c, around ae-binimport-%d-%d). When the import is refused, for example by ae_refuse_split_ownership or ae_lib_check_compat, the refusal calls exit(1) and the directory stays behind.
To see it on Windows: build a static-runtime library whose export passes a struct holding a string, import it from a program, and run ae build. The build is refused, as it should be, and %TEMP%\ae-binimport-<pid>-0 is left with the stub in it. Every refused build leaves one more.
Expected: a refused import removes its stub directory, as a build that succeeds does.
Found while reviewing #3477; not part of it.

Today's came from tests whose imports are refused by design: abi_policy (fake.ae), binary_import_ownership (rec.ae,frees.ae), binary_import_structs (engine.ae), abi_matrix (mlib.ae). So every local run of those tests adds a few, and CI runners do too.fix: a refused binary import removes its stub directory (#3485)
