update uvwasi to version 0.0.11 (#167)

Notable changes:

- The uvwasi_preopen_t now uses const char* for the mapped_path
  and real_path fields. Previously, these were not const.
- uvwasi_path_filestat_get() now properly handles the
  UVWASI_LOOKUP_SYMLINK_FOLLOW flag.
- uvwasi_options_init() has been added to reduce the boilerplate
  code associated with initializing uvwasi_options_t's.
- The DEBUG() macro has been renamed to UVWASI_DEBUG() to reduce
  naming conflicts with other projects.
- The uvwasi_fd_filestat_set_times() and
  uvwasi_path_filestat_set_times() functions now have proper
  implementations.
- Several issues have been addressed in uvwasi_fd_readdir().
  A bug in the copying of the directory entry's name has been
  fixed. The function now returns UVWASI_ENOSYS on Windows and
  Android. Serdes support has been added for uvwasi_dirent_t's.
- The libuv dependency has been updated to v1.39.0.
