Rebuild crosvm with fixed minijail

Previous builds were not using the prebuilt, and minijail
was being built incorrectly using host glibc features in a non-hermetic
way. Fix the Cargo build of minijail-sys to use a shared library and fix
the shared library to use the same prebuilt intermediates that
Android.bp uses.

This restores proper functionality of the crosvm sandbox while still
only requiring glibc 2.8.
