bp4dbg: executable

Created by: ax3l

Mark the installed Python scripts related to bp4dbg as executable.

This mitigates an audit error in homebrew/linuxbrew of the form:

adios2:
  * Non-executables were installed to "/home/axel/src/brew/opt/adios2/bin"
    The offending files are:
      /home/axel/src/brew/opt/adios2/bin/bp4dbg
Error: 1 problem in 1 formula detected

But generally it does not look clean to install a directory bp4dbg/ inside bin/. Is there a way to clean this up or disable this?
