Fix linked glibc version in Linux (JVM) builds

[cedrickcooke]

Spun up a Raspberry Pi to test #989, and Sensortag scans crash immediately. JNA fails to load kable-btleplug-ffi because the binary is linked with glibc 2.38, but Raspberry Pi OS only has glibc up to 2.36.

Easiest solution is probably building with cross on the Linux runners. At time of writing, their default toolchain is on glibc 2.31 and they also provide a toolchain built on centos 7/glibc 2.17
