greybus: interface: fix potential attribute-buffer overflow

Use scnprintf in the generic attribute helper, which does not currently
check for buffer overflow.

The attribute helper is used to print generic strings, which could
potentially overflow the buffer. Note that the only strings currently
exported are taken from greybus string descriptors and should therefore
be limited to 255 chars.
