qmake: Guard module depends with __cplusplus

When qtbase has been compiled with PCH and trying to compile the
disassembler in QtDeclarative creating the PCH for "C" is failing
due the C++ includes. Guard the includes with __cplusplus to be
"usable" on C code. This guard is proposed for the "stable.h" in
the qmake precompiledheaders documentation.
