fixes #692 bootloader module fails when /EFI/Boot exists

Browse Source 
- to make it short - it doesn't help much if one try to find and process any
  EFI related things in the live system. The better approach is to search in
  the chroot.
- use python builtins for mkdir and cp
- replacing some subprocess calls
- Some PEP8 changes
- added myself to the copyright section
