sys-devel/llvm: Update live ebuild, fix Python install

Update the patches and install procedure for git changes. Switch to
python-single-r1 as most of the Python components are now installed
by CMake.

+Subject: [PATCH] llvm-config: Clean up exported values, update for shared
+ linking
+
+Gentoo-specific fixup for llvm-config, including:
+- wiping build-specific CFLAGS, CXXFLAGS,
+- updating library suffixes for shared libs,
+- wiping --system-libs for shared linking,
+- banning --obj-root and --src-root due to no sources installed.
+
+Thanks to Steven Newbury for the initial patch.
