Clean up LLVM bundle package: don't use wildcards and exclude unneeded libs.

Hopefully this won't break too many things. Libraries removed:

- Linux: removed ~5.5MB from ~24.5MB of libs (excluding Android libs):
1.5M	libclang_rt.asan-i386.so
4.0K	libclang_rt.asan-preinit-i386.a
1.5M	libclang_rt.asan-x86_64.so
4.0K	libclang_rt.asan-preinit-x86_64.a
36K	libclang_rt.hwasan_cxx-x86_64.a
4.0K	libclang_rt.hwasan_cxx-x86_64.a.syms
1.4M	libclang_rt.hwasan-x86_64.a
4.0K	libclang_rt.hwasan-x86_64.a.syms
388K	libclang_rt.hwasan-x86_64.so
352K	libclang_rt.ubsan_standalone-i386.so
332K	libclang_rt.ubsan_standalone-x86_64.so

- Darwin: removed ~3MB from ~9MB of libs
1.5M	libclang_rt.fuzzer_no_main_ios.a
1.6M	libclang_rt.fuzzer_no_main_iossim.a

- Windows: (insignificant) removed ~50KB from ~28MB of libs
48094	clang_rt.asan-preinit-i386.lib
892	clang_rt.asan-preinit-x86_64.lib
