Track Typora as a real package, drop OPT_JSONHEADmaster

Typora now ships as the typora-bin Slackware package from my-slackbuilds, so
its installed version comes from /var/log/packages like everything else. The
OPT_JSON map existed solely to read /opt/Typora-linux-x64/resources/package.json
and is removed along with its branch in installed_of().

Typora joins through both alias maps instead: ALIAS for the installed package
name and REPO_ALIAS for the SlackBuild directory, both typora-bin. The stanza
is marked # repo=my.
