Add infrastructure required for Linux coredump support
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. Reviewed By: kib Sponsored By: EPSRC Differential Revision: https://reviews.freebsd.org/D30921
