[gupnp] [PATCH] Workaround for broken printf() implementations.

[Sven Neumann <s neumann raumfeld com>]

Explicitly add 24 zeros for the 24 reserved hex-digits in DLNA.ORG_FLAGS.
The previous implementation used the format string "%.8x%.24x". This
causes a crash in the gnulib vasprintf() implementation shipped with GLib.
The new code is less demanding on the printf implementation and hopefully
also easier to read.
