Subject: [PATCH] jq: disable failing time conversion test on 32 bit

jq upstream has a test right on 32 bit epoch end [1].
On i686-linux, this test is executed because it is a native build.
However, the test will fail on 32 bit.
The *good* solution is to build jq with 64 bit time representation.
That might break with dynamic linking though, so instead we just disable this test.
Note: this is a bit of a hack!
