Tar: for directories, use a default mask that has the 'x' bit.

Without the 'x'-bit, the directories that get created are not accessible.

Do we need a test that untars something containing a directory and then tries to access it, e.g. copying something inside it, reading something from it, etc.? It sounds like that would fail without this fix?

Yes, it would fail without the fix.
The existing tests have the expected permission hard coded, so they'll also fail if this regresses.

LGTM. I ran the runtime-extra-platforms pipeline, to make sure all the exotic platforms pass too.
If it all looks good, we can merge it.

No tar failures.
