elf files created by perf inject are not read correctly

[lievenhey]

Describe the bug hotspot cant read the symbols created by perf inject.

failed to report elf for pid = 118447 : ElfInfo{localFile="/home/lieven/.debug/tmp/jitted-118447-38.so/062a186662248dc7250a8b3a99466d52e08db2df/elf", isFile=true, originalFileName="jitted-118447-38.so", originalPath="/tmp/jitted-118447-38.so", addr=7f9a85782570, len=80, pgoff=40, baseAddr=n/a} : No ELF program headers

To Reproduce

1. create a file named test.dart with the following content:

void main() {
  print("Hello World");
}

2. run perf record --call-graph dwarf -k 1 dart --generate-perf-jitdump test.dart
3. run perf inject -j -i perf.data -o perf.data.jitted
4. read a book or two
5. open perf.data.jitted with hotspot

Expected behavior hotspot is able to read the files created by perf inject

Screenshots If applicable, add screenshots to help explain your problem.

objdump can also open that file
