After the libdwfl conversion, we apply ELF relocations with libdwfl
instead of our homegrown implementation. However, libdwfl is much slower
at it than the previous implementation. We can work around this by
(again) applying ELF relocations ourselves for architectures that we
care about (x86-64, to start). For other architectures, we can fall back
to libdwfl.
This new implementation of ELF relocation reworks the parallelization to
be per-file rather than per-relocation. The latter was done originally
because before commit 6f16ab09d6 ("libdrgn: only apply ELF relocations
to relocatable files"), we applied relocations to vmlinux, which is much
larger than most kernel modules. Now that we don't do that, it seems to
be slightly faster to parallelize by file.
