pkgbuild: cleanup clang build feature
Mostly shell code cleanup, the compiler check up top is much more robust
and the other references can be simplified. Clang built packages are now
easily identified by '+clang' appended to the pkgver.
DKMS hasn't released a version yet that's compatible with LLVM built
kernels so most people are going to want to beware of these unless
they've modified their local DKMS scripts.
