src/locktest: add missing struct cast with syscall getsockname()

The usage of variable 'myAddr' (struct sockaddr_in) is being casted into a
'struct sockaddr' when used with bind() and with connect().  This patch
adds that cast when used with getsockname() as well, otherwise we'll get the
following error:

locktest.c: In function 'main':
locktest.c:1155:39: error: passing argument 2 of 'getsockname' from incompatible pointer type [-Wincompatible-pointer-types]
