Fix UAVCAN bootloader builds broken by os calls from stm32_flash

Browse Source 
Recent upsteam NuttX changes needed by PX4 added sem_[wait|post]
   in the stm32_flash driver.

   UAVCAN Bootloaders do not use the OS's scheduler etal.
   This commit nops the sem_[wait|post] with linker magic.
   Which precludes the linking the nuttx scheduler in the
   bootloader build.
