audio/libmusicbrainz5: Update to snapshot from 2015-07-06 (e29cc9a)
- The main purpose of this intermediate update is to eliminate unwanted debug
information emitted when running console applications.
- Backport commit 36262d6 to eliminate wildcards for dependencies in
CMakeLists.txt which CMake complains about (CMP0058). As a result, we can
switch to an outsource build.
- Update LICENSE (LGPL21+) and add LICENSE_FILE
- Remake/rename patches with 'make makepatch'
