[PATCH 3/7] objtool: Move macros describing structures to arch-dependent code

[Julien Thierry]

Some macros are defined to describe the size and layout of structures
exception_table_entry, jump_entry and alt_instr. These values can vary
from one architecture to another.

Have the values be defined by arch specific code.
