For direct-to-ELF snapshots, the story remains the same as before,
as we use the information from the Image header if available.
If it isn't, then we fall back to dladdr to get the dynamic shared
object containing the app snapshot and then walk the ELF or Mach-O
headers to find the build ID or UUID information.
