Remove Cppcheck from the distribution

I was initially impressed with its output, but over time I've found it
less and less useful. I hardly use it anymore, and it would at best be
neglected if left in the distribution. The build script is retained in
the contrib/ directory, and it's easy to build natively from source.

-## Cppcheck tips
-
-Use `--library=windows` for programs calling the Win32 API directly, which
-adds additional checks. In general, the following configuration is a good
-default for programs developed using w64devkit:
-
-    $ cppcheck --quiet -j$(nproc) --library=windows \
-               --suppress=uninitvar --enable=portability,performance .
-
-A "strict" check that is more thorough, but more false positives:
-
-    $ cppcheck --quiet -j$(nproc) --library=windows \
-          --enable=portability,performance,style \
-          --suppress=uninitvar --suppress=unusedStructMember \
