spec: keep .BTF section in modules for s390

The patch 6a8653ed6b34 ("spec: Keep .BTF section in modules")
introduced possibility to keep .BTF sections which is necessary for
CONFIG_DEBUG_INFO_BTF option.

At that time s390 architecture had a problem (see the 6a8653ed6b34
commit message), which was later fixed with efdd3eb8015e ("libbpf:
Accommodate DWARF/compiler bug with duplicated structs").

c446fdacb10d ("bpf: fix register_btf_kfunc_id_set for
!CONFIG_DEBUG_INFO_BTF") made such modules unloadable.

The patch removes the workaround since it's not needed anymore.
