BmapCopy: Fix unconditional initialization of _bmap_path

Fix the initialization of instance variable _bmap_path by renaming
the only occurrence of _f_bmap_path in the constructor of class
BmapCopy.

The naming scheme (_f_bmap, _bmap_path) is now consistent with
(_f_dest, _dest_path) and (_f_image, _image_path) declared later in
the BmapCopy constructor.
