fp->size_cmd is set to allocated memory in kftp_parse_url() but this is not freed by knet_close(). The fix should be safe in other cases as these allocate the memory of fp via calloc leaving fp->size_cmd equal to NULL by default, and free(NULL) is a nop (https://linux.die.net/man/3/free).

Adds a test that builds knetfile.c.

If the test for that builds knetfile.c is too instrusive/hackish, it can be dropped.
