s390/extable: convert to relative table with data
Follow arm64, riscv, and x86 and change extable layout to common
"relative table with data". This allows to get rid of s390 specific
code in sorttable.c.
The main difference to before is that extable entries do not contain a
relative function pointer anymore. Instead data and type fields are
added.
The type field is used to indicate which exception handler needs to be
called, while the data field is currently unused.
