checkpatch: make the CamelCase cache work for non-git trees too
Might as well check include timestamps and cache the include file CamelCase uses for the non-git case too. The camelcase cache file is now named: for git: .checkpatch-camelcase.git.<commit_id> for non-git: .checkpatch-camelcase.date.<YYYYMMDDhhmm> All .checkpatch-camelcase* files are deleted if not current.
