linux-generic: add <bits/msq.h> and <bits/shm.h>.
Just like the other architectures, we need to avoid adding the padding fields for the time_t fields in shmid_ds and msqid_ds. The linux-generic versions are exactly like the x86_64 versions, except I added a missing #include <bits/wordsize.h> in <bits/msq.h>.
