[Reproducible-builds] Bug#792596: jsmath: please make the build reproducible

Hi,

While working on the "reproducible builds" effort [1], we have noticed
that jsmath could not be built reproducibly.

The attached patch removes timezone-varying timestamps from the
files extracted with unzip. Once applied, jsmath can be built
reproducibly in our reproducible toolchain.
