libefivar: Fix (some) typos

Fix typos in the files that are owned by the project.

Bring back a "duplicate word" removal (node node), which should have
been "node Node", the second "node" is not capitalized in the reference
file (yet).  We'll bring it back capitalized to avoid it from triggering
automated checking scripts and possibly reverting this change again.  A
few other typos were not fixed, as we strive to keep as close to the
reference files as possible, these fixes should be submitted to the
reference project (tianocore/edk2) in the not so distant future.

 a much better match for plain narrow characters on FreeBSD. So we pretend that
 CHAR16 for these files is really char * (ASCII).
