[patch] Fix `make clean` error

[h_east]

Hi Bram and list,

When execute `make clean` after `make test`, an error is output.
The attached patch fixes this.
Please confirm.

PS
testdir/Make_{dos,ming}.mak had already taken measures.

--------8<--------
$ make
[...]
$ make test
[...]
$ make clean
rm -rf *.out *.failed *.res *.rej *.orig
rm -f opt_test.vim test.log test_result.log messages
rm -f test.out X* viminfo tiny.vim small.vim mbyte.vim mzscheme.vim test.ok benchmark.out
rm: cannot remove 'XfakeHOME': Is a directory
Makefile:87: recipe for target 'clean' failed
make: [clean] Error 1 (ignored)
rm -f valgrind.*

Thanks. I had noticed that XfakeHOME was left behind, but had not
looked into fixing that yet.

I notice Make_amiga.mak deletes /tmp/*, that doesn't seem like a good
idea... Maybe it was OK when running one thing at a time, Amiga
replacements are more like Unix.
