｢dir｣ dies if weird unicode sequences are encountered (dir;)

From @AlexDaniel

One-liner to reproduce the bug (preferably run it in an empty directory)​:

perl -E 'mkdir pack "h*", "60ba"'; perl6 -e 'dir; say �hello�'

Result​:
Malformed UTF-8 at line 1 col 2
  in block <unit> at -e line 1

It should not die. Such file (or directory) exists and all operations with it should work.

I've reproduced that on linux with ext4 filesystem. ugexe confirmed it.

It was reported that this bug is not reproducible with that one-liner on OS X​:
<ParsonsNose> AlexDaniel I get no errors. it just makes a directory called ^F%AB/ ..

Windows gives no error, and doesn't appear to make the directory

I hesitate to put a test for this in...
Closing as resolved anyway.

Explanation and ideas on IRC​: https://irclog.perlgeek.de/moarvm/2017-03-02#i_14193748

- It's risky to be part of normal tests, lest the user won't be able to delete these weird dirs
- Setup `make risky-test` target that would run these risky tests only when user asks (knowing they're on a system that can be trashed freely)

Test added in Raku/roast@a7590d6

Note that the test *does create* files with weird names, but that's totally OK in /tmp I think.
