inject.sh: split up the inject functions
generally go for a more linear function order, and split up any functions. the objective is to have functions only suitable to libreboot be separate. more splitting will be done, and eventually the vendor-download functions will be split into a new file, as will several other functions. this is being done as part of an effort to bring the libreboot and canoeboot versions of inject.sh in sync, so that from now on, cherry picking between the two projects will produce fewer merge conflicts and require a lesser amount of post-merge maintenance. some other minor cleanup has also been done; for example, the "need_files" variable is redundant and was removed.
