This patch rewrites the last few users of prog_locate() to access CBFS
APIs directly and removes the call. This eliminates the double-meaning
of prog_rdev() (referring to both the boot medium where the program is
stored before loading, and the memory area where it is loaded after) and
makes sure that programs are always located and loaded in a single
operation. This makes CBFS verification easier to implement and secure
because it avoids leaking a raw rdev of unverified data outside the CBFS
core code.

This patch removes the prog_locate() step for stages and rmodules.
Instead, the stage and rmodule loading functions will now perform the
locate step directly together with the actual loading. The long-term
goal of this is to eliminate prog_locate() (and the rdev member in
struct prog that it fills) completely in order to make CBFS verification
code safer and its security guarantees easier to follow. prog_locate()
is the main remaining use case where a raw rdev of CBFS file data
"leaks" out of cbfs.c into other code, and that other code needs to
manually make sure that the contents of the rdev get verified during
loading. By eliminating this step and moving all code that directly
deals with file data into cbfs.c, we can concentrate the code that needs
to worry about file data hashing (and needs access to cbfs_private.h
APIs) into one file, making it easier to keep track of and reason about.
This patch is the first step of this move, later patches will do the
same for SELFs and other program types.

The --alignment flag is currently only handled by cbfstool add, but
there seems little reason to not handle it for all file-adding commands
(the help text actually mentions it for add-stage as well but it doesn't
currently work there). This patch moves the related code (and the
related baseaddress handling) into cbfs_add_component(). As a nice side
effect this allows us to rearrange cbfs_add_component() such that we can
conclusively determine whether we need a hash attribute before trying to
align the file, allowing that code to correctly infer the final header
size even when a hash attribute was implicitly added (for an image built
with CBFS verification enabled).
