staprun was actually loading the module, but it passed a user privilege level
of pr_stapdev to the module as the user's privilege level. Since pr_stapdev
does not contain pr_stapsys, the module's self checking code determined that
the user did not have sufficient privileges to run it, and so it aborted.
staprun should have passed a privilege level of pr_all to the module, ensuring
that all modules within the special directory can be run by all users. More
accurately, the user must at a minimum be a member of stapusr, since staprun
itself can only be run by root or members of that group.
commit 019e44d6bf7137af289412f35f28be5938acfb62 implements this fix.
