So I think [this code](https://searchfox.org/mozilla-central/rev/f40d29a11f2eb4685256b59934e637012ea6fb78/tools/profiler/lul/platform-linux-lul.cpp#48-54) needs to be special-cased for libraries whose name is `[vdso]`. We need to treat the bytes in our process memory from `lib.GetStart()` to `lib.GetEnd()` as a normal ELF file. The Lul ELF section loading code needs to support the case where we already have the bytes for the file and it does not need to be loaded from the file system.
