rG435754a59ee2: Add infrastructure required for Linux coredump support

Summary

This adds sv_elf_core_osabi, sv_elf_core_abi_vendor,
and sv_elf_core_prepare_notes fields to struct sysentvec,
and modifies imgact_elf.c to make use of them instead of hardcoding
FreeBSD-specific values. It also updates all of the ABI definitions
to preserve current behaviour.

This makes it possible to implement non-native ELF coredump support
without unnecessary code duplication. It will be used for Linux
coredumps.

Note that this is essentialy a part of https://reviews.freebsd.org/D30019, with Linux-specific bits changed back to FreeBSD-specific ones to preserve old behaviour, and also to make them build.

sys/sys/imgact_elf.h
106	I suggest to rename this type, it is too generic for elf-specific usage.
