salhelper: change oslCondition to osl::Condition

Condition is deprecated already, but there is no need for the
us to use the low-level C-API, when in fact there is a C++ fascade
that calls on this via the C++ abstraction, osl::Condition.

This will make it much easier to switch to using std::condition_variable
