[dev.boringcrypto] crypto/internal/boring: remove .llvm_addrsig section

Browse Source 
The section doesn't survive some of the mangling of the object file we
do while building it, and ld.lld --icf=safe throws a warning on it.

Could have changed the clang invocation to add -fno-addrsig, but this
change is safer in that it doesn't affect the FIPS module build.
