not completely integrated with DKMS

[R-Chandra]

In the subdirectory awusb, there is a dkms.conf, but the Makefile only works for the currently running kernel (because it calls "uname -r"). Wish I knew how I might submit a suggested fix directly, but "git push" says I don't have permission. So, instead I offer this diff:

diff --recursive --unified sunxi-livesuite/awusb/Makefile sunxi-livesuite-local/awusb/Makefile
