Make file picker mode work also for non-text files.

[hsanson]

Some editors (e.g. vim/neovim) are capable of opening and editing non text files such as xlsx, and even gcc dumps. Also the mime type sometimes is not identified properly (e.g. tex/latex files) that result in the editor opening external programs instead of opening the file in the editor.

When running in file picker mode (fff -p) it sould open any file in the editor independently of the mime type. The following simple patch implements the change:
