bytereader, bytewriter: fix up inline functions to make g++ happy

gstbytereader.h: In function ‘guint8* gst_byte_reader_dup_data_unchecked(GstByteReader*, guint)’:
gstbytereader.h:249:75: error: invalid conversion from ‘void*’ to ‘guint8*’
gstbytewriter.h: In function ‘gboolean _gst_byte_writer_ensure_free_space_inline(GstByteWriter*, guint)’:
gstbytewriter.h:196:75: error: invalid conversion from ‘void*’ to ‘guint8*’
