Add -usehd to excluded args in check-doc.py #11285

All Travis builds on master are currently failing due to contrib/devtools/check-doc.py picking up -usehd in src/wallet/wallet.cpp#L3845 as an undocumented argument (removed in #11250). Just need to add it to the list of unsupported, deprecated and duplicate args in check-doc.py so that it's ignored. Otherwise all builds on top of #11250 will fail until this is merged.

Failing as below, however it looks like it's only the arm-linux builds?

0.08s$ if [ "$CHECK_DOC" = 1 ]; then contrib/devtools/check-doc.py; fi
Args used        : 145
Args documented  : 172
Args undocumented: 1
set(['-usehd'])
Args unknown     : 28

The command "if [ "$CHECK_DOC" = 1 ]; then contrib/devtools/check-doc.py; fi" failed and exited with 1 during .
Your build has been stopped.

@fanquake it's only on the builds which export CHECK_DOC=1 to run check-doc.py

Does a reminder need to be added to the docs somewhere, so this doesn't happen again?

Unsure where it would be suitable to put such a thing, but if you have a place in mind it would probably be a good idea :+1:

This problem should have been fixed in #11250 where travis should be broken (but the build was cancelled) so I guess there is no need for documentation.
