OpenRCT2: update to 0.3.4, enable tests
https://github.com/void-linux/void-packages/pull/32050

Description:
In the last version, a few of the tests were broken, so I hadn't put in the plumbing for the check step yet. Now the tests all pass, so that's cool.

Also, I removed `/usr/lib/libopenrct2.a`, which only exists to be linked into `openrct2` and `openrct2-cli` and shouldn't have been included in the package itself. (It can also be built as a shared object, but again it's only used to share code between the two binaries, and I'm not going to try to reconcile that with Void policy over 10M of duplicated code.)
