linux-user: fix emulation of accept4/getpeername/getsockname/recvfrom syscalls
System calls that return a socket address do so by writing the (possibly
truncated) address into the provided buffer space, but setting the
addrlen parameter to the actual size of the address. To determine how
much to copy back to the target memory the emulation needs to remember
the incoming value of the addrlen parameter, so that it doesn't write
past the buffer limits.
