ELF, uapi: fixup ELF_ST_TYPE definition
This is very theoretical compile failure:
ELF_ST_TYPE(st_info = A)
Cast will bind first and st_info will stop being lvalue:
error: lvalue required as left operand of assignment
Given that the only use of this macro is
ELF_ST_TYPE(sym->st_info)
where st_info is "unsigned char" I've decided to remove cast especially
given that companion macro ELF_ST_BIND doesn't use cast.
