pcu_sock: add some guard space to message buffer 

in osmo-pcu, the message buffer in pcu_sock_read is allocated with 1000
bytes in addition to the true size of the pcu_prim struct. Presumably
this is to avoid compatibility problems in case the primitives slightly
grow due to appending new struct members. Lets do the same in osmo-bts.
