infra: msan enable PIC

[maflcko]

Not sure why LLVM_ENABLE_PIC needs to be enabled manually. It should be by default, according to https://llvm.org/docs/CMake.html#llvm-related-variables

Not sure about the failures. They are network related timeouts, or coverage/address sanitizer related. However, I only changed the cmake_libcxx function that builds msan and 32-bit libcxx. So those failures seem unrelated?

[maflcko]

mbedtls is already failing, so the failure here is unrelated: https://oss-fuzz-build-logs.storage.googleapis.com/index.html#mbedtls

[maflcko]

All other failures are also happening already, so this should be good to go?

Annoying that there's a False positive in trial builds due to ARM.
