cmd/link: invalidate kernel cache on darwin
Apparently, the darwin kernel may cache the code signature at
mmap. When we mmap the output buffer, it doesn't have a code
signature (as we haven't generated one). Invalidate the kernel
cache after writing the file.
See https://github.com/golang/go/issues/42684#issuecomment-731704900
for more information.
Updates #38485.
Fixes #42684.
