s390/kaslr: add support for R_390_GLOB_DAT relocation type
Commit "bpf: Process in-kernel BTF" in linux-next introduced an undefined
__weak symbol, which results in an R_390_GLOB_DAT relocation type. That
is not yet handled by the KASLR relocation code, and the kernel stops with
the message "Unknown relocation type".
Add code to detect and handle R_390_GLOB_DAT relocation types and undefined
symbols.
