x264enc: Strip trailing whitespace from x264's log messages

x264 has linebreaks at the end of its log messages that we should
ignore.

Add G_GNUC_PRINTF to the callback to make sure GCC lets us forward the
format string to another function marked as printf (g_strdup_vprintf)
without triggering -Wformat-nonliteral.
