[PATCH v4 07/19] bootstd: Update bootmeth_alloc_file() to record images

[Simon Glass]

As a first step to recording images and where they came from, update
this function to do so, since it is used by two bootmeths

Create a helper function in the bootflow system, since recorded
images are always associated with bootflows.
