Unbreak test in 3.4.1with fileflags patch

[rosorio]

Hi,

I found an issue running the tests of FreeBSD where fileflags is enabled.
The patch create two incompatibles declaration of module_dirlen if t_stub.c
since RsyncProject/rsync@fa28c5d

I add a patch in top of my fork who integrates 3.4.1 changes who are not available in the current repo
as reported in issue #11.
