Resolve microseconds_t ambiguity 1/2 
This resolves a PBD vs ARDOUR namespace error for some compilers:
```
error: reference to 'microseconds_t' is ambiguous
libs/pbd/pbd/microseconds.h:29:19: error: candidates are: typedef uint64_t PBD::microseconds_t
libs/ardour/ardour/types.h:81:29: error:                  typedef PBD::microseconds_t ARDOUR::microseconds_t
```
