Bug#935387: libdrumstick: Copyright attributions missing from debian/copyright

[Scott Kitterman]

Source: libdrumstick
Version: 0.5.0-3
Severity: serious
Justification: Policy 2.3

In cmake_admin, the copyright holders for FindSharedMimeInfo.cmake and
MacroEnsureVersion.cmake are missing from debian/copyright.  Since
listing these is a requirement of the license of the files (BSD), it's a
policy 2.3 requirement.

Note: found during New review of 1.1.2-1.  Filing this in lieu of
rejecting from New since it's now a new issue in the package.
