[PATCH 2/2] notes: revert note_data.given behavior with empty notes add

[David Disseldorp <ddiss@suse.de>]

Prior to 90bc19b3ae, note_data.given was set alongside an -m, -C or -F
parameter for add / append. Following 90bc19b3ae, note_data.given is
only set if the notes data buffer length is non-zero, which results in
GIT_EDITOR invocation if e.g. a zero length blob object is provided.

Revert to pre-90bc19b3ae note_data.given behavior, to fix
non-interactive callers.

Fixes: 90bc19b3ae ("notes.c: introduce '--separator=<paragraph-break>' option")
