Properly convert objects between different ELF classes

Properly convert objects between different ELF classes

The output SHF_COMPRESSED section size is different from input if
ELF classes of input and output aren't the same.  We must adjust
the section sizes as well as the compression headers in
SHF_COMPRESSED sections when converting objects between different
ELF classes.
