struct ipc_perm, as used by shmctl() when soing shared memory stuff,

struct ipc_perm, as used by shmctl() when soing shared memory stuff,
was incorrect in uClibc, and was 2 bytes too short.  This caused uClibc
shared memory stuff to not behave correctly since struct ipc_perm was
included as the first member of, i.e. struct msqid_ds, so the content
of that struct were all shifted by two bytes.  ugh.  Apparently, few
people have used shared memory, msgctl(), etc with uClibc thus far,
