Linkers (ld.bfd/gold/lld) place the section header table at the very
end. This allows tools to strip it, which is optional in executable/shared objects.
In addition, if we add or section, the size of the section header table
will change. Placing the section header table in the end keeps section
offsets unchanged.
yaml2obj currently places the section header table immediately after the
program header. Follow what linkers do to make offset updating easier.

This patch touches a few test cases:
It removes dtflags.elf-x86-64 binary and elf-dtflags.test.
elf-dtflags.test is excessive because we have the
elf-dynamic-tags.test which test all non-machine specific tags.
It removes testing of --dynamic-table from test\Object\readobj-shared-object.test
(we have the elf-dynamic-tags.test for that), and simplifies this test case.
It moves testing of the headers from readobj-shared-object.test
to elf-file-headers.test.
Adds test/tools/llvm-readobj/elf-file-types.test and test/tools/llvm-readobj/elf-loadname.test.
It opens road for removing the readobj-shared-object.test completely soon.
