checkpatch: cache last camelcase hash as .checkpatch-camelcase.<commit>
Add a file to cache the CamelCase variables found by <commit> to reduce
the time it takes to scan the include/ directory.
Filename is '.checkpatch-camelcase.<commit>' and it is created only only
if a .git directory exists.
<commit> is determined by the last non-merge commit id in the
include/ path.
Reduces checkpatch run time by ~12 cpu seconds on my little netbook.
