Patch can patch files in subdirectories as long as two conditions hold:

1) You generate the patch such that the subdirectories are included as
part of the filenames on the *** or --- lines of a context diff, or an
Index: line with other kinds of diffs.  (It looks like your diff file
satisfied this condition.)

2) The person applying the patch has to say "patch -p" to tell patch to
pay attention to the pathnames.  (I think this is all you needed.)
