bitbake: bin/bitbake: add a check for /dev/shm existing
Python multiprocessing needs /dev/shm, and if it doesn't exist (e.g. in a chroot environment) or is not writable, you'll get "OSError: [Errno 38] Function not implemented" or "OSError: [Errno 13] Permission denied" with a traceback, which doesn't really help to explain what is wrong. Implements [YOCTO #4407].
