Check if noexec is enabled before loading native libraries

Use case or motivation behind the feature request

Getting errors like .cache/JNA/temp/jna2624433973614287324.tmp: failed to map segment from shared object: Operation not permitted

due to noexec being enabled in $HOME, stacktrace points it to being jpr_01

This doesn't seem to be a bug but I am also not sure how feasible it is to do a self sanity check
