util/cbfstool: Remove existing file for add-int command

Since add-int is intended for manipulating options stored as integers in
CBFS (such as SeaBIOS runtime config options), removing the file so that
it can be re-added with a new value is a common action. Attempt to
remove the existing integer automatically if it already exists to remove
the need for the extra step.
