staging: Avoid sysroot removal races

Currently a task could remove a dependency needed by another task leading
to build failures, often due to missing dependencies (e.g. dynamic libraries
not being found). This was often seen for all-arch recipes in package_write_rpm.

When removing a dependency, first check that no other task active for the
recipe has that same dependency.
