Revert "Bug 1875294 - Record breadbcrumbs before crashing with UnsatsisfiedLinkError"

This reverts commit 6fb061ce5efc1a3fb11dace06b826382e0b56736.

These didn't work out in practice.  The file lists were always empty, I
think it might be a difference in permissions for release builds vs the
debug builds that I was testing with.

The package installer name was useful, but I realized there's Sentry tag for that which is even more useful.
