indent: Fix spelling

--

These are non-substantive corrections for minor spelling mistakes
within the GnuPG codebase.

With something like this applied to the codebase, and a judiciously
tuned spellchecker integrated as part of a standard test suite, it
should be possible to keep a uniform orthography within the project.
