[models] install unconditionally

Summary: Since D20891116 (https://github.com/facebook/infer/commit/224e0b7c521f0e7ecdb524b6a5ab6fa056a2706d), java models are not installed at all if the C analyzers are not enabled.  The recent move of models into Sqlite (D23191601 (https://github.com/facebook/infer/commit/1db53f43b5ab41e4b4a3a5c6338d0a36e86b028f)) makes this a fatal error instead of a silent one.
