qtest: Be paranoid about accept() addrlen argument

POSIX specifies that address_len shall on output specify the length of
the stored address; it does not however specify whether it may get
updated on failure as well to, e.g., zero.

In case EINTR occurs, re-initialize the variable to the desired value.
