- Fixed libbsd feature test confusion.
Rationale: users expressed confusion when using the old "--without-libbsd" configure flag. Some assumed that it compiles scrot without libbsd, but it only made the build script error if libbsd is a dependency. This is useful to package maintainers: it gives them a yes/no answer on whether the library is a dependency on their system. The old configure flag has been replaced by a more verbose "--enable-libbsd-feature-test".
- Fixed 'make dist', adding some files to bootstrapped tarballs.
