subprojects: Prepare for release

When running on rootful systems. This brings dccb612 back to life.
It was broken in 8108d4d, which fixed two Interceptor singleton leaks.
Turns out the one in springboard.m was intentional, as it was done as
part of init-once logic, with no teardown intended. And since nothing
else uses Interceptor in this case, the instrumentation we just
applied gets reverted right away.

Kudo to @alexhude for reporting.
