Userland: Fix unnecessary heap allocation of singleton objects

Browse source 
In order to avoid having multiple instances, we were keeping a pointer
to these singleton objects and only allocating them when it was null.

We have `__cxa_guard_{acquire,release}` in the userland, so there's no
need to do this dance, as the compiler will ensure that the constructors
are only called once.
