binman: Use the Makefile for u_boot_ucode_ptr

Remove this file from git and instead build it using the Makefile.

Update tools.GetInputFilename() to support reading files from an absolute
path, so that we can read the Elf test files easily. Also make sure that
the temp directory is report in ELF tests as this was commented out.
