tools vm: Fix build due to removal of tools/lib/api/fs/debugfs.h

There were some changes in how this debugfs mounting helper is
implemented/exported and we forgot to check if there were other users
besides perf, fix it.

Need to do a make -C tools/ everytime we do changes to
tools/{lib,include} and other places where we're moving things from
tools/perf/ to be used by other tools/ living code.


  $ make -C tools/vm

  make -C ../lib/api
