Exclude unhandled files

[klaaspieter]

When including DeviceKit as a dependency SPM warns about unhandled files:

warning: 'devicekit': found 1 file(s) which are unhandled; explicitly declare them as resources or exclude from the target
/Users/kp/Developer/clones/DeviceKit/Tests/Info.plist
warning: 'devicekit': found 1 file(s) which are unhandled; explicitly declare them as resources or exclude from the target
/Users/kp/Developer/clones/DeviceKit/Source/Device.swift.gyb

Pull request overview

This PR updates the SwiftPM manifest to explicitly exclude non-source files that SPM previously warned as "unhandled" when consuming DeviceKit as a dependency.

Changes:

• Exclude Info.plist and Device.swift.gyb from the main DeviceKit target so they are no longer reported as unhandled files.
• Exclude Info.plist from the DeviceKitTests test target to eliminate the corresponding SPM warning.

@Zandor300 anything I can do about the danger failure?
