Add missing relocation types & architectures for ELF

[Roeegg2]

Is your feature request related to a problem? Please describe.
The code under file librz/bin/p/bin_elf.inc function reloc_convert which takes care of moving data from RzBinElfReloc to the general RzBinReloc doesn't take care of some relocation architectures (CRIS, Nios II, HPPA, and many more) and as well misses many relocation types in all of the currently implemented relocations

Describe the solution you'd like
Simply adding switches/cases to reloc_convert take of these architectures/types

Describe alternatives you've considered
N/A

Additional context

Same thing for patch_reloc. A lot types and archs aren't handled there

HPPA will be covered by #4469

We need to add the missing architectures and types in COFF as well... Maybe we should just unite them into one issue?
Both shouldn't take very long and aren't very hard to fix.
