Currently we have to set 'Machine' to something in our
YAML descriptions. Usually we use 'EM_X86_64' for 64-bit targets
and 'EM_386' for 32-bit targets. At the same time, in fact, in most
cases our tests do not need a machine type and we can use
'EM_NONE'.
This is cleaner, because avoids the need of using a particular machine.
In this patch I've made the 'Machine' key optional (the default value,
when it is not specified is `EM_NONE`) and removed it (where possible)
from yaml2obj, obj2yaml and llvm-readobj tests.
There are few tests left where I decided not to remove it, because
I didn't want to touch CHECK lines or doing anything more complex
than a removing a "Machine: *" line and formatting lines around.

We have an issue currently: --dyn-relocations always prints the following
relocation header when dumping `DynPLTRelRegion`:
"Offset Info Type Symbol's Value Symbol's Name + Addend"
I.e. even for an empty object, --dyn-relocations still prints this.
It is a easy to fix bug, but we have no dedicated test case for this option.
(we have a dynamic-reloc-no-section-headers.test, which has a slightly different purpose).
This patch adds a test and fixes the behavior.
