Try the following:
\let\oldcaption\caption
\def\takeshort#1.#2\next{\gdef\short{#1}\gdef\everything{{\bfseries #1}.~~#2}}
\def\caption#1{\takeshort#1\next\oldcaption[\short]{\everything}}

Because \bfseries doesn't take an argument. It affects everything in its
scope, so the trick is limiting the scope by braces.
Note that the above macros also work when there is only one dot in the
caption. In this case, maybe you don't want a boldened caption, so the
following could be more appropriate:
\let\oldcaption\caption
\def\takeshort#1.#2\next{\gdef\short{#1}\def\two{#2\relax}%
\gdef\everything{\if\two\relax #1.\else{\bfseries #1}.~~#2\fi}}
\def\caption#1{\takeshort#1\next\oldcaption[\short]{\everything}}
