binman: Correct symbol calculation with non-zero image base

At present binman adds the image base address to the symbol value before
it writes it to the binary. This is not correct since the symbol value
itself (e.g. image position) has no relationship to the image base.

Fix this and update the tests to cover this case.

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.

SPDX: Convert all of our single license tags to Linux Kernel style

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents. There's also a few places where I found we did not have a tag
and have introduced one.

binman: Add tests binaries with binman symbols

For testing we need to build some ELF files containing binman symbols. Add
these to the Makefile and check in the binaries:

u_boot_binman_syms - normal, valid ELF file
u_boot_binman_syms_bad - missing the __image_copy_start symbol
u_boot_binman_syms_size - has a binman symbol with an invalid size
