package/opusfile: bump to version 0.11

Changes since the v0.10 release:

- Fix two potential integer overflows. (These were not
  security-critical unless the compiler took the opportunity provided
  by the undefined behavior to format your hard drive.)
- Allow JPEGs in METADATA_BLOCK_PICTURE tags to include EXIF data.
- A few warning fixes for gcc 8.
- Make opus_tags_copy return OP_EFAULT on failure instead of returning
  success.
- Various integration and testing environment improvements.

This release is backward-compatible with the previous release. We
recommend all users upgrade.
