[PATCH 1/2] fsdev/9p-marshal: move G_GNUC_PRINTF to header

[Sean Wei <me@sean.taipei>]

v9fs_string_sprintf() is annotated with G_GNUC_PRINTF(2, 3) in
9p-marshal.c, but the prototype in fsdev/9p-marshal.h is missing the
attribute, so callers that include only the header do not get format
checking.

Move the annotation to the header and delete the duplicate in the
source file. No behavior change.
