Fix configure.ac of wrong configure error message

[AndersonKao]

What

fixing --with-docs-only to --with-only-docs

Why ?

Because I encounter this error while trying to build the docs.
configure: error: --with-only-docs was requested, but doxygen was not found
Here is my running command

./autogen.sh
./configure --prefix=/tmp/ucc --with-docs-only

The correct error message should be
configure: error: --with-docs-only was requested, but doxygen was not found

Thank you @Sergei-Lebedev for pointing out my mistake on the previous wrong PR. #294

You can sign and send it to admin@ucfconsortium.org and send a copy to me. Are you on the UCC slack channel? I can DM my email id there. If you want to join the slack channel, please let me know, where to provide the slack invite.

Sorry for the really late reply, I was too busy during this semester so I forgot to reply to this. I just sent the CLA. Is this enough for you to merge the PR? Looking forward to receiving your reply.
