package/rtl8821au: bump version and remove debugging patch

This patch updates rtl8821au to include an upstream commit which
disables debug output, unless a runtime insmod parameter debug=level
is passed when loading the module. This makes the old buildroot patch
to remove hardcoded debug defines unnecessary: as such, it has been
removed.
