compiletest: Delete the executable immediately after running.

This should save a lot of space on musl test cases (whose standard library
are linked statically).

As you expected, the musl disk usage for run-pass alone drops from 24 GB to 6 GB after applying this.

Can you check if this means we no longer skip tests that we've already run? Today if you run ./x.py test src/test/run-pass twice then the second run all of the tests will be ignored -- does this PR preserve that?

One might want to run the binary manually if the test fails (e.g., under a debugger). Could there be an opt-out, or could this be restricted to only apply to successful tests?

Delete executables if the test ran successfully.

This isn't a perfect heuristic, but since the amount of run-fail tests
is far lower than run-pass tests for now, it should be sufficient to
ensure that we don't run into CI limits. This makes it possible to run
the test binary manually (e.g., under gdb/lldb) if it failed to attempt
to find out why.
