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 removes 2 precompiled objects from the test case and replaces
them with a single YAML. That allowed to simplify and clean up the test,
remove excessive checks.

GNU readelf tool prints slightly different dynamic table "header" and
surrounds dynamic tag names by brackets. This patch implements the same
formatting for GNU-style output of the `llvm-readobj`.
LLVM
```
DynamicSection [ (13 entries)
Tag Type Name/Value
0x00000006 SYMTAB 0x168
...
]
```
GNU
```
Dynamic section at offset 0x1d0 contains 13 entries:
Tag Type Name/Value
0x00000006 (SYMTAB) 0x168
...
```

Summary: Currently, `llvm-readobj` do not support GNU style dumper for symbol versioning sections. In this patch, I would like to implement dumper for `.gnu.version` section

Summary:
Currently, llvm-readobj can dump symbol version sections only in LLVM style. In this patch, I would like to separate these dumpers into GNU style and
LLVM style for future implementation.

This reverts commit 94a0cffe250c1cd6b8fea5607be502cadf617bdc (r356764).
This change was originally committed in r356764, but then partially
reverted in r356777 due to "bad changes". This caused test failures
because the test changes committed along with the original change
were not reverted, so this change reverts the rest of the changes.

This patch changes single method of llvm-readobj.
It teaches SHT_GNU_verdef dumper to print version dependencies,
also it removes few fields from output that can be dumped with other keys
and slightly refactors code.
Testcase was also modified to match the changes.
Change is required for testcases of upcoming lld patches.

SHT_GNU_verneed (.gnu.version_r) is a version dependency section.
It was the last symbol versioning relative section that was not dumped,
now it is.
