fix duplicated definition of boolean_t

It is defined both in openair2/COMMON/commonDef.h and
openair2/COMMON/platform_types.h.

Removing one or the other definition creates many problems
when compiling this or that part of the system (ue_ip.ko,
at_nas_ue). Let's keep both and protect the definitions
inside #ifdefs.
