gsctool: allow multiple source files
With the upcoming extensions it would be beneficial to be able to keep
gsctool functionality spread among multiple source files. The current
Makefile is also not generating proper dependencies, which was fine
when gsctool utility was first introduced, but is not adequate any
more, and would be even more noticeable when more source files are
added.
In preparation let's just convert the build scheme into separately
compiling .c files, generating .d files while at it, and then linking
the .o files together in a separate link operation.
BRANCH=none
BUG=chromium:812880
TEST=verified that gsctool still builds fine and allows to update Cr50
image.
