BaseTools/GenFds: permit stripped MM_CORE_STANDALONE binaries

The standalone MM core is executed in place, and resides in a
separate execution context which may be space constrained.
Since code and data may be mapped with different attributes for
security reasons, the PE/COFF binary could have a section
alignment of 4 KB.

This means that any relocation data is not only useless, but it
will also take up 4 KB of valuable space.

So add support for the RELOCS_STRIPPED attribute on FFS files of
this type, so that we can get rid of the .reloc section altogether.
