Simplify codespellrc, fix remaining typos

Current .codespellrc contains too many exclusions, and as a result it
misses some legitimate typos.

A few previous commits silenced or fixed some of the codespell warnings
in preparation for this one, which minimizes exclusions, and fixes the
actual remaining typos.

The fixes here are the result of codespell -w.

./copy/sign_test.go:119: overidden ==> overridden
./copy/encryption.go:51: pratice ==> practice
./copy/multiple_test.go:80: crated ==> created
./copy/progress_bars.go:124: progres ==> progress
