selftests/coredump: Fix "socket_detect_userspace_client" test failure
The coredump.socket_detect_userspace_client test occasionally fails:
    #  RUN           coredump.socket_detect_userspace_client ...
    # stackdump_test.c:500:socket_detect_userspace_client:Expected 0 (0) != WIFEXITED(status) (0)
    # socket_detect_userspace_client: Test terminated by assertion
    #          FAIL  coredump.socket_detect_userspace_client
    not ok 3 coredump.socket_detect_userspace_client

because there is no guarantee that client's write() happens before server's
close(). The client gets terminated SIGPIPE, and thus the test fails.

Add a read() to server to make sure server's close() doesn't happen before
client's write().
