Merge dashpay#6037: fix: bump version of libbacktrace library

0e82bf4 fix: bump version of libbacktrace library (Konstantin Akimov)

Pull request description:

  ## Issue being fixed or feature implemented
  Old version of `libbacktrace` library doesn't support debug information for ELF produced by modern compilers

  It appears like an error:
   > unrecognized DWARF version in .debug_info at 6
   > no debug info in ELF executable

  ## What was done?
  Bump version of `libbacktraces` to the current master. It doesn't seems as it has any releases anymore, so, I chose the latest revision.

  ## How Has This Been Tested?
  With old version:
  ```
  No debug information available for stacktrace. You should add debug information and then run
  dashd -printcrashinfo=bvcgc43iinzgc43ijfxgm3ybaacwiyltnbsfw43umq5du5dfojwws3tborssqkjamnqwy3dfmqqgi5lfeb2g6idvnzugc3tenrswiidfpbrwk4dunfxw4csfpbrwk4dunfxw4oraor4xazj5mnugc4ramnxw443ufiwca53imf2d2isiiveekiqed56acaaaaaaaaucrlszzcfaaaaevexftsekaaafvmqbaaaaaaaaaa===
  ```

  With this fixes output as expected:
  ```
  std::terminate() called due to unhandled exception
  Exception: type=char const*, what="HEHE"
