binman: Use the Makefile for u_boot_binman_syms

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

With this change a few things need to be adjusted:

1. The 'notes' section no-longer appears at the start of the ELF file
(before the code), so update testSymbols to adjust the offsets.

2. The dynamic linker is disabled to avoid errors like:

    "Not enough room for program headers, try linking with -N"

3. The interpreter note is moved to the end of the image, so that the
binman symbols appear first.
